The law required, (1.) That on the morrow after the Passover Sabbath a sheaf of new corn should be waved by the priest before the altar (Lev. 23:5, Lev. 23: 6, 10, 12;2:12).

(2.) That at the feast of Pentecost two loaves of leavened bread, made from the new flour, were to be waved in like manner (Lev. 23:15, Lev. 23: 17; Num. 28:26).

(3.) The feast of Tabernacles was an acknowledgement that the fruits of the harvest were from the Lord (Exo 23:16;34:22).

(4.) Every individual, besides, was required to consecrate to God a portion of the first-fruits of the land (Exo 22:29;23:19;34:26; Num. 15:20, Num. 15: 21).

(5.) The law enjoined that no fruit was to be gathered from newly-planted fruit-trees for the first three years, and that the first-fruits of the fourth year were to be consecrated to the Lord (Lev. 19:23). Jeremiah (2:3) alludes to the ordinance of "first-fruits," and hence he must have been acquainted with the books of Exodus, Leviticus, and Numbers, where the laws regarding it are recorded.
