Judges 20:16-18

Young's Literal Translation

¹⁶ among all this people [are] seven hundred chosen men, bound of their right hand, each of these slinging with a stone at the hair, and he doth not err.

¹⁷ And the men of Israel numbered themselves, apart from Benjamin, four hundred thousand men, drawing sword, each of these a man of war.

¹⁸ And they rise and go up to Beth-El, and ask of God, and the sons of Israel say, `Who doth go up for us at the commencement to battle with the sons of Benjamin?' and Jehovah saith, `Judah -- at the commencement.'
