Numbers 31:41 reports the execution: Moses gave the tribute to Eleazar exactly as commanded in this verse.

Numbers 18:26 also involves a heave offering (terumah) given to the priest from the Levites' tithe — same term and recipient as the offering here.

Numbers 18:19 declares heave offerings a perpetual covenant for priests; here Eleazar receives the tribute as a heave offering, applying that statute.

Exodus 29:28 establishes the heave offering as perpetual due for priests; here the Midian spoil tribute is given to Eleazar as a heave offering.

Leviticus 7:14 specifies that one heave offering from peace offerings belongs to the priest; similarly the tribute from the spoil is given to the priest Eleazar.
