Old corn of the land - Rather “produce of the land,” the new grain just coming in at the time of the Passover. (So in Joshua 5:12.)
On the morrow after the passover - These words denote in Numbers 33:3 the 15th Nisan, but must here apparently mean the 16th. For the Israelites could not lawfully eat of the new grain until the first fruits of it had been presented, and this was done on “the morrow after the Sabbath,” i. e. the morrow after the first day of Unleavened Bread, which was to be observed as a Sabbath, and is therefore so called. (Compare Leviticus 23:7, Leviticus 23:11, Leviticus 23:14.)
The term Passover, which is sometimes used for the lamb slain on the evening of the 14th Nisan, sometimes for the paschal meal, sometimes for the whole eight days’ festival, here means the first great day of the eight, the Sabbath of the first holy convocation.
