II Samuel 7:12-13

12 And when your days be fulfilled, and you shall sleep with your fathers, I will set up your seed after you, which shall proceed out of your bowels, and I will establish his kingdom.
13 He shall build a house for My name, and I will establish the throne of his kingdom for ever.

The words of the Lord Jesus in Revelation 3:7 should be noted, “These things says He that has the key of David, He that opens, and no man shuts; and shuts, and no man opens;”
