“He shall wave the sheaf [omer] before the Lord, for acceptance on your behalf; on the day after the sabbath the priest shall wave it” (Leviticus 23:11). “He shall wave the sheaf [omer] before the Lord.” How would he wave it? Rabbi Ḥama bar Ukva said in the name of Rabbi Yosei ben Rabbi Ḥanina: He would wave it to and fro and raise and lower it. He would wave it to and fro, to the One to Whom the entire world belongs. He would raise and lower it, to the One to whom the heavenly and the earthly belong. Rabbi Simon ben Rabbi Yehoshua said: He would wave it to and fro to eliminate harmful winds. He would raise and lower it to eliminate harmful dews.
