'Separate' in the Bible

he shall separate himself from wine and strong drink: he shall drink no vinegar of wine, nor vinegar of strong drink, neither shall he drink any liquor of grapes, nor eat grapes, fresh or dried.

And thou shalt separate the Levites from among the children of Israel, that the Levites may be mine.

Separate yourselves from the midst of this assembly, and I will consume them in a moment.
