Psalms 68:28

Thy God, O Israel, hath commanded Hath ordained, or effectually procured; thy strength All that strength and power which thou hast effectually exerted at any time against thine enemies, and which is now greatly increased by the union of all the tribes under one head. In other words, the great power of the Israelites, and the height of glory and strength to which the kingdom of David had arisen, were the work of God. This naturally makes way for the petition following: Strengthen, O God, that which thou hast wrought in us Let the foundation of our present happiness be firm and durable.
