Orthodox Jewish Bible

¹⁷ And the ish Yisroel, apart from Binyamin, mustered 400,000 men armed with cherev; all these were ish milchamah.

¹⁸ And the Bnei Yisroel arose, and went up to Beit-El, and asked counsel of Elohim, and said, Which of us shall go up first to the milchamah against the Bnei Binyamin? And Hashem said, Yehudah shall go up first.

¹⁹ And the Bnei Yisroel rose up in the boker, and encamped against Giv’ah.
