2 Samuel 7:11, 27

even from the day that I appointed judges over My people Israel; and I will give you rest from all your enemies. The LORD also declares to you that He will make a house (royal dynasty) for you.

For You, O LORD of hosts, God of Israel, have revealed this to Your servant, saying, ‘I will build you a house (royal dynasty).’ For that reason Your servant has found courage to pray this prayer to You.
