Who was Tola?
(1) Tola was one of the four sons of Issachar (Gen 46:13; 1 Ch 7:1), mentioned among those who journeyed to Egypt with Jacob (Gen 46:8 f), and in the census taken by Moses and Eleazar, as father of the Tolaites (Nu 26:23) whose descendants in the reign of David included 22,600 "mighty men of valor" (1 Ch 7:2).
(2) One of the Judges, the son of Puah, a man of Isaachar. He dwelt in the hill country of Ephraim in the village of Shamir, where after judging Israel 23 years he was buried (Jdg 10:1,2). In the order of succession he is placed between Abimelech and Jair. It is interesting to note that both Tola and Puah are names of colors, and that they occur together both in the case of the judge and in that of the sons of Isaachar. They may therefore be looked upon as popular typical or ancestral names of the Issachar tribe, although current critical theories seek an explanation in a confusion of texts.
