In the beginning David commends himself to the protection of God. He then meditates upon the benefits which he received from God, and thereby stirs himself up to thanksgiving. By his service, it is true, he could in no respect be profitable to God, but he, notwithstanding, surrenders and devotes himself entirely to him, protesting that he will have nothing to do with superstitions. He also states the reason of this to be, that full and substantial happiness consists in resting in God alone, who never suffers his own people to want any good thing.
Mictam of David.
As to the meaning of the word mictam, the Jewish expositors are not of one mind. Some derive it from כתם, catham, 1 as if it were a golden crest or jewel. Others think it is the beginning of a song, which at that time was very common. To others it seems rather to be some kind of tune, and this opinion I am inclined to adopt.
Psalm 16:1
1. Keep [or guard 2 ] me, O God; for in thee do I trust. 3
This is a prayer in which David commits himself to the protection of God. He does not, however, here implore the aid of God, in some particular emergency, as he often does in other psalms, but he beseeches him to show himself his protector during the whole course of his life, and indeed our safety both in life and in death depends entirely upon our being under the protection of God. What follows concerning trust, signifies much the same thing as if the Holy Spirit assured us by the mouth of David, that God is ready to succor all of us, provided we rely upon him with a sure and steadfast faith; and that he takes under his protection none but those who commit themselves to him with their whole heart. At the same time, we must be reminded that David, supported by this trust, continued firm and unmoved amidst all the storms of adversity with which he was buffeted.
Psalm 16:2-3
2. Thou shalt say unto Jehovah, Thou art my Lord, my well-doing extendeth not unto thee. 3. Unto the saints who are on the earth, and to the excellent; all my delight is in them.
2. Thou shalt say unto Jehovah. David begins by stating that he can bestow nothing upon God, not only because God stands in no need of any thing, but also because mortal man cannot merit the favor of God by any service which he can perform to him. At the same time, however, he takes courage, and, as God accepts our devotion, and the service which we yield to him, David protests that he will be one of his servants. To encourage himself the more effectually to this duty he speaks to his own soul; for the Hebrew word which is rendered Thou shalt say, is of the feminine gender, which can refer only to the soul. 4 Some may prefer reading the word in the past tense, Thou hast said, which I think is unobjectionable, for the Psalmist is speaking of an affliction which had a continued abode in his soul. The import of his language is, I am, indeed, fully convinced in my heart, and know assuredly, that God can derive no profit or advantage from me; but notwithstanding this, I will join myself in fellowship with the saints, that with one accord we may worship him by the sacrifices of praise. Two things are distinctly laid down in this verse. The first is, that God has a right to require of us whatever he pleases, seeing we are wholly bound to Him as our rightful proprietor and Lord. David, by ascribing to him the power and the dominion of Lord, declares that both himself and all he possessed are the property of God. The other particular contained in this verse is, the acknowledgement which the Psalmist makes of his own indigence. My well-doing extendeth not unto thee. Interpreters expound this last clause in two ways. As עליך, aleyka, may be rendered upon thee, some draw from it this sense, that God is not brought under obligation, or in the least degree indebted to us, by any good deeds which we may perform to him; and they understand the term goodness in a passive sense, as if David affirmed that whatever goodness he received from God did not proceed from any obligation he had laid God under, or from any merit which he possessed. But I think the sentence has a more extensive meaning, namely, that let men strive ever so much to lay themselves out for God, yet they can bring no advantage to him. Our goodness extendeth not to him, not only because, having in himself alone an all-sufficiency, he stands in need of nothing, 5 but also because we are empty and destitute of all good things, and have nothing with which to show ourselves liberal towards him. From this doctrine, however, the other point which I have before touched upon will follow, namely, that it is impossible for men, by any merits of their own, to bring God under obligation to them, so as to make him their debtor. The sum of the discourse is, that when we come before God, we must lay aside all presumption. When we imagine that there is any good thing in us, we need not wonder if he reject us, as we thus take away from him a principal part of the honor which is his due. But, on the contrary, if we acknowledge that all the services which we can yield him are in themselves things of nought, and undeserving of any recompense, this humility is as a perfume of a sweet odour, which will procure for them acceptance with God.
