Stand therefore. Now follows a description of the arms which they were enjoined to wear. We must not, however, inquire very minutely into the meaning of each word; for an allusion to military customs is all that was intended. Nothing can be more idle than the extraordinary pains which some have taken to discover the reason why righteousness is made a breastplate, instead of a girdle. Paul's design was to touch briefly on the most important points required in a Christian, and to adapt them to the comparison which he had already used. Truth, which means sincerity of mind, is compared to a girdle. Now, a girdle was, in ancient times, one of the most important parts of military armor. Our attention is thus directed to the fountain of sincerity; for the purity of the gospel ought to remove from our minds all guile, and from our hearts all hypocrisy. Secondly, he recommends righteousness, and desires that it should be a breastplate for protecting the breast. Some imagine that this refers to a freely bestowed righteousness, or the imputation of righteousness, by which pardon of sin is obtained. But such matters ought not, I think, to have been mentioned on the present occasion; for the subject now under discussion is a blameless life. He enjoins us to be adorned, first, with integrity, and next with a devout and holy life.

Stand therefore - Resist every attack - as a soldier does in battle. In what way they were to do this, and how they were to be armed, the apostle proceeds to specify; and in doing it, gives a description of the ancient armor of a soldier.
Having your loins girt about - The "girdle, or sash," was always with the ancients an important part of their dress, in war as well as in peace. They wore loose, flowing robes; and it became necessary to gird them up when they traveled, or ran, or labored. The girdle was often highly ornamented, and was the place where they carried their money, their sword, their pipe, their writing instruments, etc.; see the notes on Matthew 5:38-41. The "girdle" seems sometimes to have been a cincture of iron or steel, and designed to keep every part of the armor in its place, and to gird the soldier on every side.
With truth - It may not be easy to determine with entire accuracy the resemblance between the parts of the armor specified in this description, and the things with which they are compared, or to determine precisely why he compared truth to a girdle, and "righteousness" to a breast-plate, rather than why he should have chosen a different order, and compared righteousness to a girdle, etc. Perhaps in themselves there may have been no special reason for this arrangement, but the object may have been merely to specify the different parts of the armor of a soldier, and to compare them with the weapons which Christians were to use, though the comparison should be made somewhat at random. In some of the cases, however, we can see a particular significancy in the comparisons which are made; and it may not be improper to make suggestions of that kind as we go along. The idea here may be, that as the girdle was the bracer up, or support of the body, so truth is suited to brace us up, and to gird us for constancy and firmness. The girdle kept all the parts of the armor in their proper place, and preserved firmness and consistency in the dress; and so truth might serve to give consistency and firmness to our conduct. "Great," says Grotius, "is the laxity of falsehood; truth binds the man." Truth preserves a man from those lax views of morals, of duty and of religion, which leave him exposed to every assault. It makes the soul sincere, firm, constant, and always on its guard. A man who has no consistent views of truth, is just the man for the adversary successfully to assail.
And having on the breast-plate - The word rendered here as "breastplate" θώρἀξ thōrax denoted the "cuirass," Lat.: lorica, or coat of mail; i. e., the armor that covered the body from the neck to the thighs, and consisted of two parts, one covering the front and the other the back. It was made of rings, or in the form of scales, or of plates, so fastened together that they, would be flexible, and yet guard the body from a sword, spear, or arrow. It is referred to in the Scriptures as a "coat of mail" 1-Samuel 17:5; an "habergeon" Nehemiah 4:16, or as a "breast-plate." We are told that Goliath's coat of mail weighed five thousand shekels of brass, or nearly one hundred and sixty pounds. It was often formed of plates of brass, laid one upon another, like the scales of a fish. The following cuts will give an idea of this ancient piece of armor.
Of righteousness - Integrity, holiness, purity of life, sincerity of piety. The breast-plate defended the vital parts of the body; and the idea here may be that the integrity of life, and righteousness of character, is as necessary to defend us from the assaults of Satan, as the coat of mail was to preserve the heart from the arrows of an enemy. It was the incorruptible integrity of Job, and, in a higher sense, of the Redeemer himself, that saved them from the temptations of the devil. And it is as true now that no one can successfully meet the power of temptation unless he is righteous, as that a soldier could not defend himself against a foe without such a coat of mail. A want of integrity will leave a man exposed to the assaults of the enemy, just as a man would be whose coat of mail was defective, or some part of which was missing. The king of Israel was smitten by an arrow sent from a bow, drawn at a venture, "between the joints of his harness" or the "breast-plate" (margin), 1-Kings 22:34; and many a man who thinks he has on the "Christian" armor is smitten in the same manner. There is some defect of character; some want of incorruptible integrity; some point that is unguarded - and that will be sure to be the point of attack by the foe. So David was tempted to commit the enormous crimes that stain his memory, and Peter to deny his Lord. So Judas was assailed, for the want of the armor of righteousness, through his avarice; and so, by some want of incorruptible integrity in a single point, many a minister of the gospel has been assailed and has fallen. It may be added here, that we need a righteousness which God alone can give; the righteousness of God our Saviour, to make us perfectly invulnerable to all the arrows of the foe.

Stand therefore - Prepare yourselves for combat, having your loins girt about with truth. He had told them before to take the whole armor of God, Ephesians 6:13, and to put on this whole armor. Having got all the pieces of it together, and the defensive parts put on, they were then to gird them close to their bodies with the ζωμα or girdle, and instead of a fine ornamented belt, such as the ancient warriors used, they were to have truth. The Gospel of Jesus Christ is the truth of God; unless this be known and conscientiously believed no man can enter the spiritual warfare with any advantage or prospect of success. By this alone we discover who our enemies are, and how they come on to attack us; and by this we know where our strength lies; and, as the truth is great, and must prevail, we are to gird ourselves with this against all false religion, and the various winds of doctrine by which cunning men and insidious devils lie in wait to deceive. Truth may be taken here for sincerity; for if a man be not conscious to himself that his heart is right before God, and that he makes no false pretences to religion, in vain does he enter the spiritual lists. This alone can give him confidence: -
- Hic murus aheneus esto,
Nil conscire sibi, nulla pallescere culpa.
Let this be my brazen wall; that no man can reproach me with a crime, and that I am conscious of my own integrity.
The breast-plate of righteousness - What the θωραξ or breast-plate was, see before. The word righteousness, δικαισυνη, we have often had occasion to note, is a word of very extensive import: it signifies the principle of righteousness; it signifies the practice of righteousness, or living a holy life; it signifies God's method of justifying sinners; and it signifies justification itself. Here it may imply a consciousness of justification through the blood of the cross; the principle of righteousness or true holiness implanted in the heart; and a holy life, a life regulated according to the testimonies of God. As the breast-plate defends the heart and lungs, and all those vital functionaries that are contained in what is called the region of the thorax; so this righteousness, this life of God in the soul of man, defends every thing on which the man's spiritual existence depends. While he possesses this principle, and acts from it, his spiritual and eternal life is secure.

Stand therefore,.... Keep your ground, do not desert the army, the church of Christ, nor his cause; continue in the station in which you are placed, keep your post, be upon your watch, stand upon your guard:
having your loins girt about with truth; by which is meant the Gospel, and the several doctrines of it; see Ephesians 1:13; and to have the loins girt with it, shows, that it should be near and close to the saints, and never departed from; and that it is a means of keeping them close to God and Christ, and of strengthening them against the assaults and attacks of Satan; and is of great use in the Christians' spiritual conflict with their enemies; the girdle is a part of armour, and so considerable as sometimes to be put for the whole, Isaiah 5:27; and here it is mentioned in the first place:
and having on the breastplate of righteousness; in allusion to Isaiah 59:17, meaning not works of righteousness done by men, though these are a fence when rightly used against the reproaches and charges of the enemy, as they were by Samuel, 1-Samuel 12:3, but rather the graces of faith and love, 1-Thessalonians 5:8, though faith has another place in the Christian armour, afterwards mentioned; wherefore it seems best to understand this of the righteousness of Christ, which being imputed by God, and received by faith, is a guard against, and repels the accusations and charges of Satan, and is a security from all wrath and condemnation.

Stand--The repetition in Ephesians 6:11, Ephesians 6:14, shows that standing, that is, maintaining our ground, not yielding or fleeing, is the grand aim of the Christian soldier. Translate as Greek, "Having girt about your loins with truth," that is, with truthfulness, sincerity, a good conscience (2-Corinthians 1:12; 1-Timothy 1:5, 1-Timothy 1:18; 1-Timothy 3:9). Truth is the band that girds up and keeps together the flowing robes, so as that the Christian soldier may be unencumbered for action. So the Passover was eaten with the loins girt, and the shoes on the feet (Exodus 12:11; compare Isaiah 5:27; Luke 12:35). Faithfulness (Septuagint, "truth") is the girdle of Messiah (Isaiah 11:5) : so truth of His followers.
having on--Greek, "having put on."
breastplate of righteousness-- (Isaiah 59:17), similarly of Messiah. "Righteousness" is here joined with "truth," as in Ephesians 5:9 : righteousness in works, truth in words [ESTIUS] (1-John 3:7). Christ's righteousness inwrought in us by the Spirit. "Faith and love," that is, faith working righteousness by love, are "the breastplate" in 1-Thessalonians 5:8.

Stand therefore . . . girt. He next gives the armor that must be worn. The Roman soldier wore a girdle, breast-plate, shoes with iron nails, a helmet to protect his head, and carried a great shield on his left arm which was thrown in front of his body. His weapon was the sword. It was with the sword, not the spear as other nations, that the Romans conquered the world. And these represent parts of the Christian's spiritual armor.
About with truth. The girdle kept the armor in place and supported the sword. So truth holds the Christian armor and supports the sword of the Spirit.
Breast-plate of righteousness. The breast-plate was over the lungs and heart. If Christ's righteousness is over our hearts they can hardly suffer harm.
And your feet shod. Not with shoes, but with the preparation to carry the gospel of peace, to be a messenger of good tidings (Isaiah 52:7).
Above all, taking the shield of faith. The Roman oblong shield, four and a half feet long, covered the whole body, and was a protection of itself. So faith, the faith that fully trusts in God and never doubts, is the best of all defenses. It will quench, stop, put out all the doubts, whisperings and evil suggestions of the wicked.
Fiery darts. These were missiles hurled by the hand, and very dangerous unless stopped by the shield.

Having your loins girt about - That ye may be ready for every motion. With truth - Not only with the truths of the gospel, but with "truth in the inward parts;" for without this all our knowledge of divine truth will prove but a poor girdle "in the evil day." So our Lord is described, Isaiah 11:5. And as a girded man is always ready to go on, so this seems to intimate an obedient heart, a ready will. Our Lord adds to the loins girded, the lights burning, Luke 12:35; showing that watching and ready obedience are the inseparable companions of faith and love. And having on the breastplate of righteousness - The righteousness of a spotless purity, in which Christ will present us faultless before God, through the merit of his own blood. With this breastplate our Lord is described, Isaiah 59:17. In the breast is the seat of conscience, which is guarded by righteousness. No armour for the back is mentioned. We are always to face our enemies.
