Judges 11:15 Meaning and Commentary

Judges 11:15

And said unto him
By his messengers:

thus saith Jephthah;
in a majestic style, as governor of Israel:

Israel took not away the land of Moab, nor the land of the children of
Ammon;
they were charged not to take any, nor did they take any that belonged to any of these countries, or that was then in the possession of either of them, ( Deuteronomy 2:9 Deuteronomy 2:19 ) what they did take was in the hands of Sihon and Og, and they had obtained it by conquest, and so no more belonging to either of these.

Judges 11:15 In-Context

13 And the king of the children of Ammon said to the messengers of Jephthae, Because Israel took my land when he went up out of Egypt, from Arnon to Jaboc, and to Jordan: now then return them peaceably and I will depart.
14 And Jephthae again sent messengers to the king of the children of Ammon,
15 and said to him, Thus says Jephthae, Israel took not the land of Moab, nor the land of the children of Ammon;
16 for in their going up out of Egypt Israel went in the wilderness as far as the sea of Siph, and came to Cades.
17 And Israel sent messengers to the king of Edom, saying, I will pass, if it please thee, by thy land: and the king of Edom complied not: and also sent to the king of Moab, and he did not consent; and Israel sojourned in Cades.
