'Separate' in the Bible

"Speak to the Israelites, and tell them, 'When either a man or a woman takes a special vow, to take a vow as a Nazirite, to separate himself to the Lord,

he must separate himself from wine and strong drink, he must drink neither vinegar made from wine nor vinegar made from strong drink, nor may he drink any juice of grapes, nor eat fresh grapes or raisins.

And so you are to separate the Levites from among the Israelites, and the Levites will be mine.

"Separate yourselves from among this community, that I may consume them in an instant."
