Joshua 5:2, 7
At that time the LORD said to Joshua, “Make flint knives and circumcise the sons of Israel once again.” / And Joshua raised up their sons in their place, and these were the ones he circumcised. Until this time they were still uncircumcised, since they had not been circumcised along the way.
