The Israelites who had returned from exile ate [it], together with all who had separated themselves from the uncleanness of the Gentiles of the land in order to worship the Lord, the God of Israel.
After these things had been done, the leaders approached me and said: "The people of Israel, the priests, and the Levites have not separated themselves from the surrounding peoples whose detestable practices are like those of the Canaanites, Hittites, Perizzites, Jebusites, Ammonites, Moabites, Egyptians, and Amorites. Indeed, they have taken some of their daughters as wives for themselves and their sons, so that the holy people has become mixed with the surrounding peoples. The leaders and officials have taken the lead in this unfaithfulness!"
Therefore, make a confession to the Lord God of your fathers and do His will. Separate yourselves from the surrounding peoples and [your] foreign wives."
When they heard the law, they separated all those of mixed descent from Israel.
2 Corinthians 6:17
Therefore, come out from among them and be separate, says the Lord; do not touch any unclean thing, and I will welcome you.
Those of Israelite descent separated themselves from all foreigners, and they stood and confessed their sins and the guilt of their fathers.
And I promised you: You will inherit their land, since I will give it to you to possess, a land flowing with milk and honey. I am the Lord your God who set you apart from the peoples.
You are to be holy to Me because I, the Lord, am holy, and I have set you apart from the nations to be Mine.
1 Kings 8:53
For You, Lord God , have set them apart as Your inheritance from all the people on earth, as You spoke through Your servant Moses when You brought their ancestors out of Egypt.
I will make a distinction between My people and your people. This sign will take place tomorrow."
I see them from the top of rocky cliffs, and I watch them from the hills. There is a people living alone; it does not consider itself among the nations.
The rest of the people-the priests, Levites, singers, gatekeepers, and temple servants, along with their wives, sons, and daughters, everyone who is able to understand and who has separated themselves from the surrounding peoples to [obey] the law of God-
In this way you are to separate the Levites from the rest of the Israelites so that the Levites will belong to Me.
Isn't it enough for you that the God of Israel has separated you from the Israelite community to bring you near to Himself, to perform the work at the Lord's tabernacle, and to stand before the community to minister to them?
"At that time the Lord set apart the tribe of Levi to carry the ark of the Lord's covenant, to stand before the Lord to serve Him, and to bless in His name, as it is today.
"Separate yourselves from this community so I may consume them instantly."
"Tell the community: Get away from the dwellings of Korah, Dathan, and Abiram."
He warned the community, "Get away now from the tents of these wicked men. Don't touch anything that belongs to them, or you will be swept away because of all their sins."
"Get away from this community so that I may consume them instantly." But they fell facedown.
1 Samuel 15:6
He warned the Kenites, "Since you showed kindness to all the Israelites when they came out of Egypt, go on and leave! Get away from the Amalekites, or I'll sweep you away with them." So the Kenites withdrew from the Amalekites.
