Judges 11:3

Then Jephthah, unable to find support among the elders of Gilead, fled from his brethren, an outcast of society, and dwelt in the land of Tob, a region toward the northeast, on the boundary of Syria; and there were gathered vain men, idle adventurers, to Jephthah, and went out with him, on expeditions of war and plunder, after the manner of the Bedouins.
