1 Kings 2:35

put in the room of Abiathar The LXX. amplifies and says that Zadok was now appointed εἰς ἱερέα πρῶτον, to be the first priest. Hitherto he seems to have had his post at Gibeon. There was not a great interval between the deposition of Abiathar and the building of the Temple, after which event the worship at Gibeon would cease. In the interval some deputy would fill Zadok's place there.

In the LXX. there is found a long additional passage here, concerning Solomon's wisdom, his marriage with Pharaoh's daughter, his offerings and sacrifices, and his buildings. Then follows almost in the words of the earlier part of this chapter (1 Kings 2:8-9) David's charge concerning Shimei. The whole insertion seems confused and purposeless.
