“Now, behold, I have taken the Levites from among the sons of Israel instead of every firstborn, the firstborn of the womb among the sons of Israel. So the Levites shall be Mine.
Aaron then shall present the Levites before the Lord as a wave offering from the sons of Israel, so that they may qualify to perform the service of the Lord.
for they are exclusively given to Me from among the sons of Israel. I have taken them for Myself instead of the firstborn of every womb, the firstborn of all the sons of Israel.
