Numbers 8:19

As a gift. — Hebrew, given, as in Numbers 8:16.

That there be no plague among the children of Israel. — The appointment of the Levites in the place of the firstborn was calculated to insure the reverent and orderly discharge of the duties of the Sanctuary, and to operate as a safeguard against those sins of omission and commission into which the firstborn would have been more likely to be betrayed, and which would have provoked the Divine wrath against the Israelites generally.
