Joshua 8:26

“For Joshua drew not his hand back wherewith he stretched out his spear, etc.] But continued it, and that stretched out: until he had utterly destroyed all the inhabitants of Ai; just as the hand of Moses was held up, and kept held up until Amalek was discomfited by Joshua, (<021712>Exodus 17:12,13).”

“Joshua drew not his hand back--Perhaps, from the long continuance of the posture, it might have been a means appointed by God, to animate the people, and kept up in the same devout spirit as Moses had shown, in lifting up his hands, until the work of slaughter had been completed--the ban executed. (See on Exo 17:10).”

“Drew not his hand back - He kept his hand and spear in the same posture, both stretched out and lifted up, as a sign both to encourage them, and to direct them to go on in the work. Joshua 8:29”

“Joshua: Joshua seems to have been not only the general but the standard-bearer of the army ( Jos 8:18), and continued in this employment, by holding up or extending his spear, during the whole of the battle; and did not slacken from the pursuit till the forces of Ai were utterly discomfited. Some commentators, however, understand this action in a figurative sense, like the holding up of Moses' hands, as if it implied that Joshua continued in prayer for the success of his troops, nor ceased till the armies of Ai were annihilated, and the city taken and destroyed. drew not: Jos 8:18; Exo 17:11, Exo 17:12 Joshua 8:27”
