2 Samuel 7:27

For thou, O Lord of hosts, God of Israel ,.... As he is called in 2 Samuel 7:26 ,

hast revealed to thy servant ; which he otherwise could not have known:

saying, I will build thee an house ; see 2 Samuel 7:11 ,

therefore hath thy servant found in his heart to pray this prayer unto thee ; found his heart disposed to this service, or found freedom and boldness in him to put up this prayer to God; what encouraged and emboldened him to do it was the gracious promise of God, that he would build up his family, and establish his kingdom; or otherwise he could not have taken such liberty, and used such boldness with God in prayer, as to have requested it of him.
