Numbers 8:16-19

Rotherham(i) 16 For, given, given, they are, unto me, out of the midst of the sons of Israel,––instead of every firstborn that a mother beareth from among the sons of Israel, have I taken them, unto me. 17 For, mine, is every firstborn, among the sons of Israel, among men, and among beasts,––on the day when I smote every firstborn in the land of Egypt, did I hallow them, unto me. 18 Therefore have I taken the Levites,––instead of every firstborn among the sons of Israel; 19 therefore have I given the Levites, as a gift unto Aaron and unto his sons, out of the midst of the sons of Israel, to do the laborious work of the sons of Israel, in the tent of meeting, and to put a propitiatory–covering over the sons of Israel,––so shall there be, among the sons of Israel, no plague, by the coming nigh of the sons of Israel unto the sanctuary.
