And when the servants of Hadarezer saw that they were put to the worse before Israel, they made peace with David, and became his servants: neither would the Syrians help the children of Ammon any more. They made peace with David, and became his servants - See on 2 Samuel 10:19 (note), and the concluding note in that place; and see for omissions in Chronicles, the preface to these books.
