TSK · Joshua 12:16

He left from there to the mountain on the east of Bethel, and pitched his tent, having Bethel on the west, and Ai on the east. There he built an altar to Yahweh and called on the name of Yahweh.

There was not a man left in Ai or Beth El who didn't go out after Israel. They left the city open, and pursued Israel.

The house of Joseph, they also went up against Bethel; and Yahweh was with them.
