And Joshua said unto the people, Sanctify yourselves: for to morrow the LORD will do wonders among you. Sanctify yourselves - What was implied in this command we are not informed; but it is likely that it was the same as that given by Moses, Exodus 19:10-14. They were to wash themselves and their garments, and abstain from every thing that might indispose their minds from a profitable attention to the miracle about to be wrought in their behalf.
