The month which the Hebrews were directed to make the first of the year in commemoration of their departure from Egypt (Ex. 12:1, 2; 13:4).
Harvest began in it.
The feast of unleavened bread or the passover fell during the month (Ex. 12:1 seq.; 23:15; Deut. 16:1).
God's calendar, with the months following the moon, and ours being fixed, the two cannot be made exactly to correspond. Abib most nearly approaches our month of March, though in some years its end moves some distance into our April. After the captivity the name Abib gave place to Nisan (Neh. 2:1; Esth. 3:7). See YEAR.
