The men of Gibeon sent to Joshua to the camp to Gilgal, saying, Don't slack your hand from your servants; come up to us quickly, and save us, and help us: for all the kings of the Amorites that dwell in the hill-country are gathered together against us.
The Gibeonites referred to the attacking coalition as, "all the kings of the hill-country," but this they probably did because Jerusalem was the leader of the coalition, and Jerusalem and Hebron were both actually in the hill-country.  Of course, we know that most of the attacking kings were from the lowlands, and, as Plummer said, "No one could have hit upon this apparent contradiction, yet real agreement, but one whose narrative was composed from authentic sources."[19]  Og and Sihon, kings of the Amorites east of Jordan, had already been defeated and slain by Israel, but the reference here to these cities of Palestine as "Amorite," is nevertheless accurate.  As Woudstra pointed out, "the term `Amorite' had a loose meaning."[20]
