Joshua 3:5 Meaning and Commentary

Joshua 3:5

And Joshua said unto the people
On the third day; and the thirtieth day of the mourning for Moses, Jarchi says, was the first of the three days, and that being the seventh day of the month, this must be the ninth, as it is most clear the morrow was the tenth:

sanctify yourselves;
in a ceremonial sense, by washing their bodies and their clothes, and abstaining from their wives; and in a moral sense, by acts of religion and devotion, by prayer and meditation, and the exercise of repentance and, good works: it may denote that sanctification is necessary to our passage over Jordan, or through death to the heavenly Canaan, for without holiness no man shall see the Lord:

for tomorrow the Lord will do wonders among you:
in their sight and presence, and for them, by dividing the waters of Jordan, that they might pass through it as on dry land; this, as Kimchi says, was the tenth of Nisan, as is plain from ( Joshua 4:19 ) .

Joshua 3:5 In-Context

3 giving these instructions to the people: “When you see the Levitical priests carrying the Ark of the Covenant of the LORD your God, move out from your positions and follow them.
4 Since you have never traveled this way before, they will guide you. Stay about half a mile behind them, keeping a clear distance between you and the Ark. Make sure you don’t come any closer.”
5 Then Joshua told the people, “Purify yourselves, for tomorrow the LORD will do great wonders among you.”
6 In the morning Joshua said to the priests, “Lift up the Ark of the Covenant and lead the people across the river.” And so they started out and went ahead of the people.
7 The LORD told Joshua, “Today I will begin to make you a great leader in the eyes of all the Israelites. They will know that I am with you, just as I was with Moses.
