Yehoshua 7:1-2

Orthodox Jewish Bible

7 But the Bnei Yisroel broke [covenant] faith in regard to the Cherem; for Achan ben Carmi ben Zavdi ben Zerach of the tribe of Yehudah, took of the Cherem (that which was devoted to destruction); and the Af Hashem was kindled against the Bnei Yisroel.

² And Yehoshua sent anashim from Yericho to Ai, which is near Beit-Aven, on the east of Beit-El, speaking unto them, saying, Go up and spy out HaAretz. And the anashim went up and spied out Ai.
