Judges 11:13

13. Israel took away my land This was probably in a certain sense tree, for, according to Joshua 13:24-25, Moses gave to the tribe of Gad half the land of the children of Ammon; and though Israel captured the land from Arnon even unto Jabbok, not of Moab nor of Ammon, but of Sihon, king of the Amorites, yet Sihon had previously fought against the king of Moab, and taken all his land out of his hand. See Numbers 21:24-26. So, though Israel strictly observed the divine order (Deuteronomy 2:9; Deuteronomy 2:19) not to disturb Moab or Ammon, they took from the Amorites lands which seem to have anciently belonged to those descendants of Lot. Israel was not to blame for conquering these lands of Sihon, and fairly owned them by the right of conquest, yet both Ammonites and Moabites might feel that they were the ancient owners. But having neglected their claim for three hundred years, (Judges 11:26,) it was idle for them to urge it now.
