Nehemiah 10:36

Also the firstborn of our sons and of our cattle ,.... Such as were unclean, as Aben Ezra notes, as the ass, &c.; and are distinguished from clean ones mentioned in the following clause; now both these, their sons, and this sort of cattle, were to be redeemed by a price paid to the priests: as it is written in the law, Exodus 13:2 ,

and the firstlings of our herds, and of our flocks ; clean cattle, which were to be offered, Numbers 18:17 ,

to bring to the house of our God, unto the priests that minister in the house of our God ; a price for the one sort, and the other for sacrifice.
