Safe - literally, as in the margin i. e., is exalted. Compare Psalm 18:2, Psalm 18:33.

The name of the Lord is a strong tower - The name of the Lord may be taken for the Lord himself; he is a strong tower, a refuge, and place of complete safety, to all that trust in him. What a strong fortress is to the besieged, the like is God to his persecuted, tempted, afflicted followers.

The name of the LORD [is] a strong tower: the righteous runneth (g) into it, and is safe.
(g) He shows the refuge of the godly against all trouble.

The name of the Lord is a strong tower,.... By "the name of the Lord" may be meant, either the attributes and perfections of God, by which he is made known, and which are the strength and security of his people; his goodness, grace, and mercy, are their defence; his favour encompasses them about, as a shield; his justice protects them from all injuries and insults; his truth and faithfulness preserve them; they are kept by his power, as in a garrison; and his unchangeableness is a reason why they are not consumed: or else the Lord himself; his name is put for himself, Psalm 20:1; and may be well interpreted of the Messiah, as it is by the ancient Jew, (q); in and by whom God is manifested unto men as the God of grace; in whom he proclaims his name, a God gracious and merciful; whose name is in him, and who has the same nature and perfections with him; his name is Jehovah, our righteousness; Immanuel, God with us; the mighty God, and Prince of peace; and who is called Jesus, because he saves his people from their sins, and so is their security from eternal destruction. What a strong tower is to them that are within it, against an enemy without, that is the power, strength, and might of Christ to his people; as a divine Person, he is strong and mighty, the most mighty, the Almighty; as man, he is the man of God's right hand, made strong for himself and us; as Mediator, he has all power in heaven and earth: in him is everlasting strength for his people; he is their Betzer, their fortified place, or city of refuge, to flee unto on all occasions; he is the strong hold, whither prisoners of hope are directed to turn to; he is their place of defence, and the munition of rocks; a strong tower, inexpugnable; so deeply founded, no enemy can work under it; and plant a mine to blow it up; so highly built; no scaling ladders can reach it; so fortified, no cannon balls can break through it, or demolish any of its walls and bulwarks, which are his salvation; the gates of hell cannot prevail against it; it is not to be taken by storm, or by the most violent attack of the whole posse of men and devils;
the righteous runneth into it; not self-righteous persons, they run from Christ and his righteousness, not to him and that; but such who see their own righteousness will not justify them; who indeed are sinners, know and acknowledge themselves to be such; as sinners go to Christ, who, as such, receives them; and these are righteous through the righteousness of Christ imputed to them, and live soberly, righteously, and godly: and it is the continual business or employment of their faith to betake themselves to Christ upon all occasions; they are continually coming to him, and exercising faith upon him, as the Lord their righteousness, which is meant by "running" to him; this supposes knowledge of him, as the strong tower and city of refuge; of the way unto him, and of the reception by him which may be expected; it supposes a principle of spiritual life, and some degree of spiritual strength; a sense of danger or of want in themselves, and of safety and fulness in Christ; it is expressive of haste, readiness, and cheerfulness, and is owing to the drawings of efficacious grace;
and such an one that thus runs
is safe; from the avenging justice of God; from the curse and condemnation of the law; from sin, and all its dreadful consequences; from Satan, and all spiritual enemies; from wrath to come, hell, and the second death: or is "set aloft" (r); is on high; for this tower, as it is a strong one, it is a high one; a rock of refuge, higher than men, or angels, or heaven itself; and such who are in it are out of the reach of all danger and every enemy.
(q) Midrash Tillim in Psal. xviii. 50. fol. 18. 1. (r) "et exaltabitur", V. L. Pagninus, Montanus, Gejerus; "erit in loco alto et tuto", Vatablus; "et exaltatur", Michaelis; "in celsoque aget", Schultens.

The Divine power, made known in and through our Lord Jesus Christ, forms a strong tower for the believer, who relies on the Lord. How deceitful the defence of the rich man, who has his portion and treasure in this world! It is a strong city and a high wall only in his own conceit; for it will fail when most in need. They will be exposed to the just wrath of that Judge whom they despised as a Saviour.

name of the Lord--manifested perfections (Psalm 8:1; Psalm 20:2), as faithfulness, power, mercy, &c., on which men rely.
is safe--literally, "set on high, out of danger" (Psalm 18:2; Psalm 91:4).

Two proverbs, of the fortress of faith, and of the fortress of presumption:
10 A strong tower is the name of Jahve;
The righteous runneth into it, and is high.
The name of Jahve is the Revelation of God, and the God of Revelation Himself, the creative and historical Revelation, and who is always continually revealing Himself; His name is His nature representing itself, and therefore capable of being described and named, before all the Tetragramm, as the Anagramm of the overruling and inworking historical being of God, as the Chiffre of His free and all-powerful government in grace and truth, as the self-naming of God the Saviour. This name, which is afterwards interwoven in the name Jesus, is מגדּל־עז (Psalm 61:4), a strong high tower bidding defiance to every hostile assault. Into this the righteous runneth, to hide himself behind its walls, and is thus lifted (perf. consec.) high above all danger (cf. ישׂגּב, Proverbs 29:25). רוּץ אל means, Job 15:26, to run against anything, רוץ, seq. acc., to invest, blockade anything, רוץ בּ, to hasten within; Hitzig's conjecture, ירוּם riseth up high, instead of ירוּץ, is a freak. רוץ בּ is speedily בוא בּ, the idea the same as Psalm 27:5; Psalm 31:21.

The name - The Lord, as he hath revealed himself in his works, and in his word by his promises.
