1 Kings 4:4

over the host Benaiah had been put into Joab's office. See 1 Kings 2:34.

Zadok and Abiatharwere the priests The Hebrew says only -were priests." Abiathar was still called priest, we may presume, after his banishment to Anathoth. The existence of two chief places for worship and sacrifice, the one at Gibeon, where the tabernacle was, and the other, where the ark was kept, on Mt Zion, had made it necessary that there should be more than one principal priest. Hence Abiathar and Zadok were in office together, and now that Abiathar was deposed, Azariah had come in as a second priest.
