And the Lord said unto Joshua - This is the same person who in the preceding chapter is called the captain or prince of the Lord's host, the discourse being here continued that was begun at the conclusion of the preceding chapter, from which the first verses of this are unnaturally divided.
I have given into thine hand Jericho, etc. - From Joshua 24:11, it seems as if there had been persons of all the seven Canaanitish nations then in Jericho, who might have come together at this time to help the king of Jericho against the invading Israelites. The Targum intimates that the place was very strong, having "gates of iron and bars of brass; and was shut up so closely that none came out, either to combat or make offers of peace."

And the Lord said unto Joshua,.... The same divine Person called in the preceding chapter the Captain of the Lord's host, Joshua 5:14, now with him, and who gave him the following orders, instructions, and assurances:
see, I have given into thy hand Jericho, and the king thereof: which might be concluded from the fear that was fallen upon the inhabitants of the city and their king, and from their shutting themselves up so closely, not daring to come out against Israel: and especially from this declaration and promise of the Lord; and which should be done in such a manner, as that it would clearly appear to be of the Lord, and not men:
and the mighty men of valour; the military men, the soldiers, or army that were under the command of the king of Jericho; or, as Kimchi reads it, "though" mighty men, yet they should not be able to defend the city, or hinder its falling into their hands; for what were they to the mighty God of Israel?

See, I have given into thine hand Jericho--The language intimates that a purpose already formed was about to be carried into immediate execution; and that, although the king and inhabitants of Jericho were fierce and experienced warriors, who would make a stout and determined resistance, the Lord promised a certain and easy victory over them.
