And Joash, and Saraph - "And the prophets and scribes which sprang from the seed of Joshua, and the Gibeonites, whose office it was to serve in the house of the sanctuary, because they had lied to the princes of Israel; also Joash, who is the same as Mahlon; and Saraph, who is the same as Chilion, who took wives of the daughters of Moab and Boaz, the chief of the wise men of the college of Bethlehem, and of those who existed in former days." - T.
Who had the dominion in Moab - Moab was conquered by David 2 Samuel 8:2, and again by Omri, after which it remained subject until the death of Ahab 2 Kings 3:5. But a more ancient rule, in times of which we have no further record, is probably intended.
