Saw that they stank— See Genesis 34:30 and 1 Chronicles 19:6. The children of Ammon, instead of apologizing, or making any reparation for the insult to David's ambassadors, joined their own forces to a Syrian army of 33,000 men, which aggravated their former outrage, and rendered them worthy of the most signal chastisement. Beth-rehob was a city belonging to the Canaanites rather than the Syrians, which stood in the tribe of Asher, though the Canaanites kept possession of it. Maacah was a city of Palestine beyond Jordan, situated in the tribe of Manasseh, and Ish-tob, which might be rendered the men of Tob, was the place whither Jephthah fled from the cruelty of his brethren, Judges 11:3.
