1 Kings 9:24
But Pharaoh's daughter came up out of the city of David unto her house which Solomon had built for her: then did he build Millo.
But Pharaoh's daughter came up out of the city of David,.... Where he placed her when he first married her, until he had finished his buildings, 1 Kings 3:1, which being done he brought her from thence unto her house, which Solomon had built for her; the reason of which is given, not only because it was the house of David, but because it was holy by the ark being there for some time; and therefore he did not judge it proper that his wife, an Egyptian woman, and sometimes in her impurity, should dwell there; see 2 Chronicles 8:11,
then did he build Millo: this being particularly repeated from 1 Kings 9:15, and following upon what is said of Pharaoh's daughter, has led many Jewish writers to conclude her house was built at Millo; and indeed, without supposing this, it is hard to conceive why it should be observed here; the Targum on 2 Chronicles 8:11 calls her name Bithiah.
