ABIATHAR, the son of Ahimelech, and the tenth high priest among the Jews, and fourth in descent from Eli, 2 Sam. viii, 17; 1 Chron. xviii, 16. When Saul sent to Nob to murder all the priests, Abiathar escaped the massacre, and fled to David in the wilderness. There he continued in the quality of high priest; but Saul, out of aversion to Ahimelech, whom he imagined to have betrayed his interests, transferred the dignity of the high priesthood from Ithamar’s family into that of Eleazar, by conferring this office upon Zadok. Thus there were, at the same time, two high priests in Israel, Abiathar with David, and Zadok with Saul. In this state things continued, until the reign of Solomon, when Abiathar, being attached to the party of Adonijah, was, by Solomon, divested of his priesthood, A. M. 2989; and the race of Zadok alone performed the functions of that office during the reign of Solomon, to the exclusion of the family of Ithamar, according to the word of the Lord to Eli, 1 Sam. ii, 30, &c. ABIB, the name of the first Hebrew sacred month, Exod. xiii, 4. This month was afterward called Nisan; it contained thirty days, and answered to part of our March and April. Abib signifies green ears of corn, or fresh fruits, according to Jerom’s translation, Exod. xiii, 4, and to the LXX. It was so named because corn, particularly barley, was in ear at that time. It was an early custom to give names to months, from the appearances of nature; and the custom is still in force among many nations. The year among the Jews commenced in September, and consequently their jubilees and other civil matters were regulated in this way, Lev. xxv, 8–10; but their sacred year began in Abib. This change took place at the redemption of Israel from Egypt, Exod. xii, 2, “This shall be to you the beginning of months.” Ravanelli observes, that as this deliverance from Egypt was a figure of the redemption of the church of Jesus Christ, who died and rose again in this month, it was made the “beginning of months,” to lead the church to expect the acceptable year of the Lord. On the tenth day of this month the paschal lamb was taken; and on the fourteenth they ate the passover. On the seven succeeding days they celebrated the feast of unleavened bread, on the last of which days they held a solemn convocation, Exod. xii, xiii. On the fifteenth they gathered the sheaf of the barley first fruits, and on the following day presented an offering of it to the Lord, which having done they might begin their harvest, Lev. xxiii.
