Numbers 3:10-13 And Aaron and his sons shalt thou instruct, that they shall guard well their priest’s office; and the stranger that cometh nigh shall be put to death.

Leeser⁽ⁱ⁾ ¹⁰ And Aaron and his sons shalt thou instruct, that they shall guard well their priest’s office; and the stranger that cometh nigh shall be put to death. ¹¹ And the Lord spoke unto Moses, saying, ¹² And I, behold, I have taken the Levites from the midst of the children of Israel instead of every first-born that openeth the womb among the children of Israel; and the Levites shall be mine. ¹³ Because mine is every first-born; on the day when I smote every first-born in the land of Egypt I hallowed unto me every first-born in Israel, both man and beast: mine shall they be; I am the Lord.
