Adam Clarke, on Neh 10:36

“And the firstborn of our sons, and of our cattle, as it is written in the law, and the firstlings of our oxen, and of our sheep, to be offered in the house of our God, to the priests who minister in the house of our God.”

“Also the first-born - See this law, and the reasons of it, Exo 13:1-13. As by this law the Lord had a right to all the firstborn, instead of these he was pleased to take the tribe of Levi for the whole; and thus the Levites served at the tabernacle and temple, instead of the first-born of all the tribes.”
