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.
The passage of the Israelites over Jordan was to be miraculous. “And Joshua said unto the people, Sanctify yourselves: for tomorrow the Lord will do wonders among you. And Joshua spake unto the priests, saying, Take up the ark of the covenant, and pass over before the people. And they took up the ark of the covenant, and went before the people. And the Lord said unto Joshua, This day will I begin to magnify thee in the sight of all Israel, that they may know that, as I was with Moses, so I will be with thee.” SR 176.1
