'Apart' in the Bible

apart from their servants and their handmaids -- these are seven thousand three hundred thirty and seven; and of them are singers and songstresses, two hundred forty and five.

All Israel in the time of Zerubbabel and in the time of Nehemiah gave allotments to each of the singers and gate keepers on a daily basis, setting them apart to benefit the descendants of Levi. And the descendants of Levi set them apart to benefit the descendants of Aaron.
