Psalms 72:18

Blessed be the Lord God - David foresaw all Solomon's grandeur; his justice equity, and the happiness of the subjects under his government; and his soul has, in consequence, sensations of pleasure and gratitude to God, which even his own wondrous pen cannot describe. But it is worthy of remark, that God did not reveal to him the apostasy of this beloved son. He did not foresee that this once holy, happy, wise, and prosperous man would be the means of debasing the Divine worship, and establishing the grossest idolatry in Israel. God hid this from his eyes, that his heart might not be grieved, and that he might die in peace. Besides, there was still much contingency in the business. God would not predict a thing as absolutely certain, which was still poised between a possibility of being and not being; the scale of which he had left, as he does all contingencies, to the free-will of his creature to turn.

Who only doeth wondrous things - God alone works miracles: wherever there is a miracle there is God. No creature can invert or suspend the course and laws of nature; this is properly the work of God. Jesus Christ, most incontrovertibly, wrought such miracles; therefore, most demonstrably, Jesus Christ is God.

Blessed be the Lord God, the God of Israel - The God who rules over Israel; the God who is worshipped by the Hebrew people, and who is recognized as their God. They adore him as the true God; and he "is" their God, their Protector, their Friend.

Who only doeth wondrous things - Things that can properly be regarded as "wonders;" things suited to excite admiration by their vastness and power. Compare Exodus 15:11.
