American Tract Society Bible Dictionary
The first month of the ecclesiastical year of the Hebrews; afterwards called Nisan. It answered nearly to our April. Abib signifies green ears of grain, or fresh fruits. It was so named, because grain, particularly barley, was in ear at the time. On the tenth of this month the passover-lamb was set apart; it was killed on the fourteenth towards sunset, and eaten the same evening after the fifteenth day had begun. The seven days from the fifteenth to the twenty-first inclusive, were "the feast of unleavened bread," closing with a solemn convocation, Exodus 12:1-13:22 .
