Albert Barnes Commentary Deuteronomy 26:2

"that thou shalt take of the first of all the fruit of the ground, which thou shalt bring in from thy land that Jehovah thy God giveth thee; and thou shalt put it in a basket, and shalt go unto the place which Jehovah thy God shall choose, to cause his name to dwell there." — Deuteronomy 26:2 (ASV)

Regarding firstfruits, see the notes at (Leviticus 23:9 and following). The firstfruits in question here are to be distinguished from both those offered in acknowledgment of the blessings of harvest at the Feasts of Passover and Pentecost, and also from the offerings prescribed in (Numbers 18:8 and following). The latter consisted of preparations from the produce of the earth, such as oil, flour, wine, etc.; while those meant here are the raw produce: the former were national and public offerings; those of this chapter were private and personal. The whole of the firstfruits belonged to the officiating priest.
