CLV(i)
16 For they are the ones being given, yea given to Me from the midst of the sons of Israel; instead of everyone opening up the womb, every firstborn of the sons of Israel, I have taken them for Myself;"
17 for Mine is every firstborn among the sons of Israel among human and among beast. On the day I smote every firstborn in the land of Egypt I sanctified them for Myself.
18 So I shall take the Levites instead of every firstborn among the sons of Israel,
19 and give the Levites from the midst of the sons of Israel as a gift to Aaron and to his sons to serve in the service on behalf of the sons of Israel in the tent of appointment and to make a separating shelter for the sons of Israel so that no stroke may come among the sons of Israel when the sons of Israel come close to the holy place.
