John Gill Commentary Nehemiah 10:35

"and to bring the first-fruits of our ground, and the first-fruits of all fruit of all manner of trees, year by year, unto the house of Jehovah;" — Nehemiah 10:35 (ASV)

And to bring the firstfruits of our ground
Not that they cast lots to do this, but they bound themselves with an oath, according to the law, to do it; this is the first of all the fruits of the earth, (Exodus 23:19) , though Aben Ezra restrains it to the sheaf of the firstfruits, and to the two wave loaves, (Leviticus 23:10Leviticus 23:17) ,

and the firstfruits of all fruit of all trees ;
which, as Aben Ezra observes, their wise men restrain to the seven kinds only mentioned in (Deuteronomy 8:8) .
