an ear of corn, the month of newly-ripened grain ( Exodus 13:4 ; 23:15 ); the first of the Jewish ecclesiastical year, and the seventh of the civil year. It began about the time of the vernal equinox, on 21st March. It was called Nisan, after the Captivity ( Nehemiah 2:1 ). On the fifteenth day of the month, harvest was begun by gathering a sheaf of barley, which was offered unto the Lord on the sixteenth ( Leviticus 23:4-11 ).
