Judges 20:29-31

Young's Literal Translation

²⁹ And Israel setteth liers in wait against Gibeah, round about,

³⁰ and the sons of Israel go up against the sons of Benjamin, on the third day, and arrange themselves against Gibeah, as time by time.

³¹ And the sons of Benjamin come out to meet the people; they have been drawn away out of the city, and begin to smite [some] of the people -- wounded as time by time, in the highways (of which one is going up to Beth-El, and the other to Gibeah in the field), [are] about thirty men of Israel.
