TSK · Exodus 17:13

For Joshua didn't draw back his hand, with which he stretched out the javelin, until he had utterly destroyed all the inhabitants of Ai.

Yahweh delivered Lachish into the hand of Israel. He took it on the second day, and struck it with the edge of the sword, with all the souls who were in it, according to all that he had done to Libnah.

Joshua took all these kings and their land at one time, because Yahweh, the God of Israel, fought for Israel.
