Nehemiah 10:35 - Joseph Benson’s Commentary on the Old and New Testaments

And to bring in the first-fruits That is, they took an oath to do it; for this is to be understood, and not that they cast lots about it, as they did about the wood-offering mentioned in the foregoing verse. All the particulars of the first-fruits are exactly and distinctly mentioned, that none might pretend ignorance when they withheld any part of the priests' dues, which, at that time especially, the people were very prone to do, through poverty, or covetousness, or profaneness, and that the priests' rights might be firmly assured to them. Thus encouragement was given to the priests to mind their duty, and care was taken that they should be under no temptation to neglect it, in order to make the necessary provision for their families. Then the work of the house of God is likely to go on, when those who serve at the altar live comfortably upon the altar.
