Psalms 50:9

9I will take no calf out thy house Two reasons are given in this and the succeeding verses to prove that he cannot set any value upon sacrifices. The first is, that supposing him to depend upon these, he needs not to be indebted for them to man, having all the fullness of the earth at his command; and the second, that he requires neither food nor drink as we do for the support of our infirm natures. Upon the first of these he insists in the ninth and three following verses, where he adverts to his own boundless possessions, that he may show his absolute independence of human offerings. He then points at the wide distinction betwixt himself and man, the latter being dependent for a frail subsistence upon meat and drink, while he is the self-existent One, and communicates life to all beside. There may be nothing new in the truths here laid down by the Psalmist; but, considering the strong propensity we have by nature to form our estimate of God from ourselves, and to degenerate into a carnal worship, they convey a lesson by no means unnecessary, and which contains profound wisdom, that man can never benefit God by any of his services, as we have seen in Psalms 16:2, “My goodness extendeth not unto thee.” In the second place, God says that he does not require any thing for his own us but that, as he is sufficient in his own perfection, he has consulted the good of man in all that he has enjoined. We have a passage in Isaiah to a similar effect,

“The heaven is my throne, and the earth is my footstool: where is the house that ye build unto me, and where is the place of my rest? For all these things hath mine hand made.” — (Isaiah 66:1,)

In these words

God asserts his absolute independence; for while the world had a beginning, he himself was from eternity. From this it follows, that as he subsisted when there was nothing without him which could contribute to his fullness, he must have in himself a glorious all-sufficiency.
