Numbers 3:41
Brenton's English Septuagint · Berean Standard Bible
And thou shalt take the Levites for me—I [am] the Lord—instead of all the first-born of the sons of Israel, and the cattle of the Levites instead of all the first-born among the cattle of the children of Israel.
You are to take the Levites for Me—I am the LORD—in place of all the firstborn of Israel, and the livestock of the Levites in place of all the firstborn of the livestock of the Israelites.”
