Matthew Henry on Joshua 2:22–end
We have here the safe return of the spies Joshua had sent, and the great encouragement they brought with them to Israel to proceed in their descent upon Canaan. Had they been disposed to discourage the people, as the evil spies did that Moses sent, they might have told them what they had observed of the height and strength of the walls of Jericho, and the extraordinary vigilance of the king of Jericho, and how narrowly they escaped out of his hands; but they were of another spirit, and, depending themselves upon the divine promise, they animated Joshua likewise. 1.

John Gill on Joshua 2:22
And they went, and came unto the mountain,.... Rahab had directed them to, the mountain Quarantania; see Gill on Joshua 2:16,

until the pursuers were returned; to the city of Jericho, as might reasonably be supposed:
and the pursuers sought them throughout all the way; from Jericho to the fords of Jordan, searching every hedge, field, and village as they went and returned:
but found them not; Rahab having hid them in her house, and then sent them to the mountain, there to remain till the return of the pursuers.
