And make straight paths, etc. He has been hitherto teaching us to lean on God's consolations, so that we may be bold and strenuous in doing what is right, as his help is our only support; he now adds to this another thing, even that we ought to walk prudently and to keep to a straight course; for indiscreet ardor is no less an evil than inactivity and softness. At the same time this straightness of the way which he recommends, is preserved when a man's mind is superior to every fear, and regards only what God approves; for fear is ever very ingenious in finding out byways. As then we seek circuitous courses, when entangled by sinful fear; so on the other hand every one who has prepared himself to endure evils, goes on in a straight way wheresoever the Lord calls him, and turns not either to the right hand or to the left. In short, he prescribes to us this rule for our conduct, -- that we are to guide our steps according to God's will, so that neither fear nor the allurements of the world, nor any other things, may draw us away from it. [1] Hence be adds, Lest that which is lame be turned out of the way, or, lest halting should go astray; that is, lest by halting ye should at length depart far from the way. He calls it halting, when men's minds fluctuate, and they devote not themselves sincerely to God. So spoke Elijah to the doubleminded who blended their own superstitions with God's worship, "How long halt ye between two opinions?" (1 Kings 18:21.) And it is a befitting way of speaking, for it is a worse thing to go astray than to halt. Nor they who begin to halt do not immediately turn from the right way, but by degrees depart from it more and more, until having been led into a diverse path so they remain entangled in the midst of Satan's labyrinth. Hence the apostle warns us to strive for the removal of this halting in due time; for if we give way to it, it will at length turn us far away from God. The words may indeed be rendered, "Lest halting should grow worse," or turn aside; but the meaning would remain the same; for what the Apostle intimates is, that those who keep not a straight course, but gradually though carelessly turn here and there, become eventually wholly alienated from God.

Footnotes

1 - Having spoken of strength, he now tells them how to use that strength. Be strong, and take a right course; go along the straight way of duty. See [49]Appendix T 2. -- Ed.

2 - This interpretation is given by Grotius, Macknight and Stuart; but Beza, Doddridge and Scott, take the view given in our version regarding the lame or weak person as intended by to cholon. So is the Vulgate, "that no one halting may go astray, but rather be healed." -- Ed

And make straight paths for your feet - Margin, "even." The word used here means properly straight, in the sense of upright, erect; Acts 14:10; but it is used here in the sense of straight horizontally, that is, level, plain, smooth. The meaning is, that they were to remove all obstacles out of the way, so that they need not stumble and fail. There is probably an allusion here to Proverbs 4:25-27. "Let thine eyes look right on, and let thine eyelids look straight before thee. Ponder the path of thy feet, and let all thy ways be established. Turn not to the right hand nor to the left; remove thy foot from evil." The idea is, that by every proper means they were to make the way to heaven as plain and easy as possible. They were to allow no obstructions in the path over which the lame and feeble might fall.
Lest that which is lame be turned out of the way - A lame man needs a smooth path to walk in. The idea is here, that everything which would prevent those in the church who were in any danger of falling - the feeble, the unestablished, the weak - from walking in the path to heaven, or which might be an occasion to them of falling, should be removed. Or it may mean, that in a road that was not level, those who were lame would be in danger of spraining, distorting, or wrenching a lame limb; and the counsel is, that whatever would have a tendency to this should be removed. Divested of the figure, the passage means, that everything should be removed which would hinder anyone from walking in the path to life.
But let it rather be healed - As in the case of lameness, pains should be taken to heal it rather than to suffer it to be increased by careless exposure to a new sprain or fracture, so it should be in our religious and moral character. Whatever is defective we should endeavor to restore to soundness, rather than to suffer the defect to be increased. Whatever is feeble in our faith or hope; whatever evil tendency there is in our hearts, we should endeavor to strengthen and amend, lest it should become worse, and we should entirely fall.

Make straight paths for your feet - That is, Take the straight path that is before you, do not go in crooked or rough ways, where are stones, briers, and thorns, by which you will be inevitably lamed, and so totally prevented from proceeding in the way; whereas, if you go in the even, proper path, though you have been wounded by getting into a wrong way, that which was wounded will be healed by moderate, equal exercise, all impediments being removed. The application of all this to a correct, holy deportment in religious life, is both natural and easy.

And make (e) straight paths for your feet, lest that which is lame be turned out of the way; but let it rather be healed.
(e) Keep a right course, and so, that you show examples of good life for others to follow.

And make straight paths for your feet,.... By "feet" are meant the walk and conversation of the saints, both in the church, and in the world, Song 7:1 and there are paths made ready for these feet to walk in; as the good old paths of truth, of the word and worship of God, of faith and holiness: and to make these paths "straight", is to make the word of God the rule of walking; to avoid carefully joining anything with it as a rule; to attend constantly on the ordinances of Christ; to go on evenly in a way of believing on him; to walk in some measure worthy of the calling wherewith we are called, and by way of example to others.
Lest that which is lame be turned out of the way; a lame member, as the Syriac version, a lame member of the body of Christ, the church; or a lame person, as the Arabic version, a weak believer; one that is ready to halt, either through the corruption of nature, or through the weakness of grace, or through want of light and judgment, and through instability and inconstancy; lest such an one should, through the irregular walk and conversation of others, be stumbled and offended, and go out of the way, and leave the paths of righteousness and truth. God takes care of, and has a regard to such, and he would have others also, Micah 4:6. The Ethiopic version reads, "that your halting may be healed, and not offended": that you yourselves may not halt and stumble.
But let it rather be healed; the fallen believer be restored, the weak brother be confirmed, the halting professor be strengthened, and everyone be built up and established upon the most holy faith, and in the pure ways of the Gospel.

Quoted from Proverbs 4:26, Septuagint, "Make straight paths for thy feet."
straight--that is, leading by a straight road to joy and grace (Hebrews 12:1-2, Hebrews 12:15). Cease to "halt" between Judaism and Christianity [BENGEL].
paths--literally, "wheel tracks." Let your walk be so firm and so unanimous in the right direction that a plain track and "highway" may be thereby established for those who accompany and follow you, to perceive and walk in (Isaiah 35:8) [ALFORD].
that which is lame--those "weak in the faith" (Romans 14:1), having still Judaizing prejudices.
be turned out of the way-- (Proverbs 4:27); and, so missing the way, lose the prize of "the race" (Hebrews 12:1).
rather he healed--Proper exercise of itself contributes to health; the habit of walking straight onward in the right way tends to healing.

And make straight paths both for your own and for their feet - Remove every hinderance, every offence. That the lame - They who are weak, scarce able to walk. Be not turned out of the way - Of faith and holiness.
