Abib

an ear of corn, the month of newly-ripened grain (Ex. 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
(Neh. 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 (Lev. 23:4-11).
