Numbers 3:10-13

Rotherham(i) 10 but, unto Aaron, and unto his sons, shalt thou give oversight, so shall they keep charge of their priesthood,––and, the stranger who cometh near, shall be put to death. 11 Then spake Yahweh unto Moses, saying–– 12 I, therefore, lo! I have taken the Levites out of the midst of the sons of Israel, instead of every firstborn that a mother beareth, from among the sons of Israel,––so shall the Levites be mine; 13 for, mine, is every firstborn, in the day when I smote every firstborn in the land of Egypt, I hallowed unto myself, every firstborn in Israel, both of man and of beast,––mine, did they become, [and belong] unto me, Yahweh.
