'Benefit' in the Bible

Also at that time men were appointed over the storerooms for the contributions, for the first fruits, and for the tithes, so those portions required by the Law could be gathered from the fields adjacent to the towns to benefit the priests and descendants of Levi, for the people of Judah rejoiced over the priests and the descendants of Levi who were serving.

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.
