And Joshua did not draw back his hand with which he stretched out the javelin until he had devoted all the inhabitants of Ai to destruction. Bible

“Joshua did not draw back his hand.” The text indicates that Joshua held his hand out so people could see the command he was giving them, and did not pull it down until the battle was over. The Keil and Delitzsch Commentary on the Old Testament notes that “the general did not lower the war-signal till the conflict was to cease.” The Bible does not explain how Joshua could hold up his hand so long; perhaps he had help, like Moses before him had (Exod. 17:10-12).
