On the subject of firstfruits see the notes at Leviticus 23:9 ff. The firstfruits here in question are to be distinguished alike from those offered in acknowledgment of the blessings of harvest (compare Exodus 22:29) at the Feasts of Passover and Pentecost, and also from the offerings prescribed in Numbers 18:8 ff. The latter consisted of preparations from the produce of the earth, such as oil, flour, wine, etc.; while those here meant 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.
