2 Samuel 7:25

And now, O LORD God, the word that thou hast spoken concerning thy servant, and concerning his house, establish [it] for ever, and do as thou hast said.

Ver. 25. Do as thou hast said.] David knew well that God's promises must be put into suit, must be prayed over. Eliah went forth to pray for rain, after He had promised it. David elsewhere saith, "Remember the word unto thy servant, upon which thou hast caused me to hope." Psa 119:49 "Lord, do as thou hast said," is a speeding argument; like Jonathan's bow, that never returned empty.
