Joshua 5:4 Meaning and Commentary

Joshua 5:4

And this [is] the cause why Joshua did circumcise
Or the reason of the command given him to circumcise the children of Israel at this time, namely, what follows:

all the people that came out of Egypt [that were] males, [even] all
the men of war;
meaning such that were twenty years old, and upwards:

died in the wilderness, by the way, after they came out of Egypt;
not directly, but in a course of forty years, as they journeyed through the wilderness; this is to be understood with an exception of Joshua, Caleb, Eleazar but then there was a large number who were under twenty years of age, that came out of Egypt, and were now living.

Joshua 5:4 In-Context

2 At that time the Lord said to Josue: Make thee knives of stone, and circumcise the second time the children of Israel.

3 He did what the Lord had commanded, and he circumcised the children of Israel in the hill of the foreskins.

4 Now this is the cause of the second circumcision: All the people that came out of Egypt that were males, all the men fit for war, died in the desert, during the time of the long going about in the way:

5

6 Now these were all circumcised. But the people that were born in the desert, During the forty years of the journey in the wide wilderness, were uncircumcised: till all they were consumed that had not heard the voice of the Lord, and to whom he had sworn before, that he would not shew them the land flowing with milk and honey.
