Psalms 16:1

This psalm is entitled Michtam, which some translate a golden psalm, a very precious one, more to be valued by us than gold, yea, than much fine gold, because it speaks so plainly of Christ and his resurrection, who is the true treasure hidden in the field of the Old Testament. I. David here flies to God's protection with a cheerful believing confidence in it (Psa 16:1): "Preserve me, O God! from the deaths, and especially from the sins, to which I am continually exposed; for in thee, and in thee only, do I put my trust." Those that by faith commit themselves to the divine care, and submit themselves to the divine guidance, have reason to hope for the benefit of both. This is applicable to Christ, who prayed, Father, save me from this hour, and trusted in God that he would deliver him. II. He recognizes his solemn dedication of himself to God as his God (Psa 16:2): "O my soul! thou hast said unto the Lord, Thou art my Lord, and therefore thou mayest venture to trust him." Note, 1. It is the duty and interest of every one of us to acknowledge the Lord for our Lord, to subject ourselves to him, and then to stay ourselves upon him. Adonai signifies My stayer, the strength of my heart. 2. This must be done with our souls: "O my soul! thou hast said it.
