(51) He is the tower of salvation.--This translation follows the margin of the Hebrew. The text is found in the ancient versions and in Psalm 18:50. "Great deliverance giveth he." The difference in the original between the consonants of the two words is extremely slight.

This brief review of these two recensions of this magnificent hymn is instructive, as showing that Providence has dealt with the MSS. of the Old Testament as with those of the New, securing them during the long succession of ages from all substantial error, and yet not so destroying ordinary human action but that mere slips of the pen should sometimes creep in, and care and diligence be required to ascertain precisely what was originally written, and sometimes, perhaps, in the merest minutiae, leaving the original form still uncertain.

The Psalm is a grand anthem of thanksgiving of David for the many mercies he had received--a full and confident expression of his trust in God under all circumstances, and of his well-assured hope in the fulfilment of the Divine promise of the perpetuity of his kingdom through the coming of Him "in whom all the families of the earth should be blessed."

22:1-51 David's psalm of thanksgiving. - This chapter is a psalm of praise; we find it afterwards nearly as Ps 18. They that trust God in the way of duty, shall find him a present help in their greatest dangers: David did so. Remarkable preservations should be particularly mentioned in our praises. We shall never be delivered from all enemies till we get to heaven. God will preserve all his people, 2Ti 4:18. Those who receive signal mercies from God, ought to give him the glory. In the day that God delivered David, he sang this song. While the mercy is fresh, and we are most affected with it, let the thank-offering be brought, to be kindled with the fire of that affection. All his joys and hopes close, as all our hopes should do, in the great Redeemer.He is the tower of salvation for his king: and showeth mercy to his anointed, unto David, and to his seed for evermore. See Gill on Psalm 18:50.
