John Gill Commentary Joshua 2:22

"And they went, and came unto the mountain, and abode there three days, until the pursuers were returned: and the pursuers sought them throughout all the way, but found them not." — Joshua 2:22 (ASV)

And they went, and came unto the mountain
Rahab had directed them to, the mountain Quarantania, (See Gill on Joshua 2:16);

and abode there three days ;
being, no doubt, supplied with food by Rahab; and it might not be three wholly, but one whole day and part of the other two:

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.
