For thou preventest him - Thou goest before him; thou dost anticipate him. See Psalms 17:13, margin. Our word “prevent” is now most commonly used in the sense of “hinder, stop, or intercept.” This is not the original meaning of the English word; and the word is never used in this sense in the Bible. The English word, when our translation was made, meant to “go before,” to “anticipate,” and this is the uniform meaning of it in our English version, as it is the meaning of the original. See the notes at Job 3:12. Compare Psalms 59:10; Psalms 79:8; Psalms 88:13; Psalms 95:2; Psalms 119:147-148; Amos 9:10; see the notes at 1 Thessalonians 4:15. The meaning here is, that God had “anticipated” him, or his desires. He had gone before him. He had designed the blessing even before it was asked.
With the blessings of goodness - Blessings “indicating” goodness on his part; blessings adapted to promote the “good” or the welfare of him on whom they were bestowed. Perhaps the meaning here is, not only that they were “good,” but they “seemed” to be good; they were not “blessings in disguise,” or blessings as the result of previous calamity and trial, but blessings where there was no trial - no shadow - no appearance of disappointment.
Thou settest a crown of pure gold on his head - This does not refer to the time of his coronation, or the period when he was crowned a king, but it refers to the victory which he had achieved, and by which he had been made truly a king. He was crowned with triumph; he was shown to be a king; the victory was like making him a king, or setting a crown of pure gold upon his head. He was now a conqueror, and was indeed a king.
