Judges 10:8-10

Young's Literal Translation

⁸ and they crush and oppress the sons of Israel in that year -- eighteen years all the sons of Israel [who] are beyond the Jordan, in the land of the Amorite, which [is] in Gilead.

⁹ And the Bene-Ammon pass over the Jordan to fight also against Judah, and against Benjamin, and against the house of Ephraim, and Israel hath great distress.

¹⁰ And the sons of Israel cry unto Jehovah, saying, `We have sinned against Thee, even because we have forsaken our God, and serve the Baalim.'
