Is this what we teach teens concerning the Aaronic Priesthood?

Behold, I have given the children of Levi all the tithes in Israel as an inheritance in return for the work which they perform, the work of the tabernacle of meeting.” (Numbers 18:21)

Or scan back a bit earlier in the instructional text,

All the best of the oil, all the best of the new wine and the grain, their firstfruits which they offer to the LORD, I have given them to you.” (Numbers 18:12).

How do you apply that to the boys?

Of course the beauty of Numbers 18 is this, when God says,

I am your portion” (Numbers 18:20).
