'Sheaf' in the Bible

"Tell the Israelis that when you enter the land that I'm about to give you and gather its produce, you are to bring a sheaf from the first portion of your harvest to the priest,

who will offer the sheaf in the LORD's presence for your acceptance. The priest is to wave it on the day after the Sabbath.

On the day you wave the sheaf, you are to offer a one year old male lamb without defect for a burnt offering in the LORD's presence.

"Starting the day after the Sabbath, count for yourselves seven weeks from the day you brought the sheaf of the wave offering. They are to be complete.
