John Gill Commentary Joshua 10:23

"And they did so, and brought forth those five kings unto him out of the cave, the king of Jerusalem, the king of Hebron, the king of Jarmuth, the king of Lachish, the king of Eglon." — Joshua 10:23 (ASV)

And they did so Opened the mouth "of" the cave, by rolling away the stones:

and brought forth those five kings to him out of the cave; who are next mentioned by name, one by one, according to their dignity, and in the order they were brought to him:

the king of Jerusalem, the king of Hebron, the king of Jarmuth, the king of Lachish, [and] the king of Eglon; who are particularly named for the greater glory of the conquest, and the triumph over them.
