Numbers 3:41

3:41 And take ¹  the Levites for me – I am the Lord – instead of all the firstborn males among the Israelites, and the livestock of the Levites instead of all the firstborn of the livestock of the Israelites.”

Numbers 3:45

3:45 “Take the Levites instead of all the firstborn males among the Israelites, and the livestock of the Levites instead of their livestock. And the Levites will be mine. I am the Lord.

[3:41]  ¹ tn The verb is the perfect tense with vav (ו) consecutive; it carries forward the instructions from the preceding verse. The verb “take” now has the sense of appointing or designating the Levites.
