Matthew Poole and continuators on Exodus 6:23

23 And Aaron took him Elishe[illegible: 1+ letters]a daughter of Aminadab , Sister of Naashon to wife, and she bare him Nadab and Abihu, Eleazar, and Ithamar.

A Prince of the Tribe of [illegible: 1 word], Numb. 1. 7. and [illegible: 1+ letters]. 3. Marriages were not yet confined to their own Tribes, and when they were, the Levites seem to have had this priviledge, th[illegible: 1+ letters] they might marry a daughter of any other tribe, because indeed the reason of that law did not concern them, there being no danger of confusion or loss of inheritance on their part. And especially there were many marriages made between the Tribes of Iudah and Levi, to signifie that both were united in Christ, who was to be both King and Priest. It is observable that Moses is here silent in his own progeny, but gives a particular account of his brothers, not onely from his great humility and modesty, which shines forth in many other passages, but because it was of more concernment, and the honour of Priesthood given to Aaron was to be hereditary and peculiar to his seed, and therefore it was necessary they should be exactly known, whereas Moses his honour and government was onely personal, and did not pass to his children.
