that the daughters of Israel went yearly to celebrate the daughter of Jephthah the Gileadite four days in a year.
"Several of the rabbins, and many very learned Christian expositors, believe that Jephthah's daughter was not really sacrificed, but that her virginity was consecrated to God, and that she separated from all connection with the world; which indeed seems to be implied in the sacred historian's account: And she knew no man. This was a kind of mysterious death, because it caused her to lose all hope of the glory of a posterity from which the Messiah might descend. From this originated the custom, observed afterwards in Israel, that on a certain season in the year the virgins assembled themselves on the mountains to bewail the daughter of Jephthah for the space of four days. Let us now consider the leading characters of the fable of Iphigenia. According to good chronological reckonings, the time of the one and of the other very nearly agree. The opinion that the name of Iphigenia is taken from the daughter of Jephthah, appears well founded; yea, the conformity is palpable. By a very inconsiderable change Iphigenia makes Iphthygenia, which signifies literally, the daughter of Jephthah. Agamemnon, who is described as a valiant warrior and admirable captain, was chosen by the Greeks for their prince and general against the Trojans, by the united consent of all Greece, assembled together at Aulis in Baeotia.
