1 Kings 3:1

Pharaoh — As being a powerful neighbour, whose daughter doubtless was first instructed in, and proselyted to the Jewish religion. It seems, this was designed by God to be a type of Christ, calling his church to himself, and to the true religion, not only out of the Jews, but even out of the Gentile world. City of David — Into David's palace there. The wall — Which though in some sort built by David, yet Solomon is here said to build, either because he made it higher, and stronger, in which sense Nebuchadnezzar is said to have built Babylon, Daniel 4:30, or because he built another wall besides the former, for after this time Jerusalem was encompassed with more walls than one.
