1 Chronicles 17:26

Thou art God. The record of this prayer in Samuel adds, “and thy words be true” (2 Samuel 7:28). David had every assurance that God’s words were sure. He prayed that God might establish His word, not because he feared that God would go back on His promise, but from a sense of deep humility and unworthiness, and because his whole heart’s desire was wrapped up with God’s desire. At the same time he was fully aware of the possibility of human failure. But as God wished it, so he desired it to be and so he prayed that it might be.
