NASB
"At that time the LORD said to Joshua, "Make for yourself flint knives and circumcise again the sons of Israel the second time.""
— Joshua 5:2, NASB
“At that time the Lord said unto Joshua, Make thee sharp knives, and circumcise again the children of Israel the second time.”
“At that time Jehovah said unto Joshua, Make thee knives of flint, and circumcise again the children of Israel the second time. ”
“At that time, Yahweh said to Joshua, "Make flint knives, and circumcise again the children of Israel the second time."”
“A New Generation is Circumcised At that time the LORD told Joshua,“Make flint knives and circumcise the Israelites once again.””
“At that time the Lord said to Joshua: Make thee knives of stone, and circumcise the second time the children of Israel.”
“At that time the Lord said to Joshua, Make yourself stone knives and give the children of Israel circumcision a second time.”
“At that time the Lord said unto Joshua, Make thee sharp knives, and circumcise again the children of Israel the second time.”
Now it came about when all the kings of the Amorites who were beyond the Jordan to the west, and all the kings of the Canaanites who were by the sea, heard how the LORD had dried up the waters of the Jordan before the sons of Israel until they had crossed, that their hearts melted, and there was no spirit in them any longer because of the sons of Israel.
At that time the LORD said to Joshua, "Make for yourself flint knives and circumcise again the sons of Israel the second time."
So Joshua made himself flint knives and circumcised the sons of Israel at Gibeath-haaraloth.
This is the reason why Joshua circumcised them: all the people who came out of Egypt who were males, all the men of war, died in the wilderness along the way after they came out of Egypt.
For all the people who came out were circumcised, but all the people who were born in the wilderness along the way as they came out of Egypt had not been circumcised.
