Midrash su Giudici 8:33

(Fol. 83b) We are taught: And they made Baal-b'rith for a god unto themselves (Jud. 8, 33). This refers to Zebub, the idol of Ekron. We learn from this that each and every one made an image of his idol [in miniature] and kept it in his pocket; whenever he was reminded of it, he took it out from his pocket and embraced and kissed it.R. Chanina b. Akabia said: "Why did the Rabbis say that a ship of the Jordan is subject to the statute of levitical uncleanliness? Because it is generally loaded on the shore and carried into the water owing to its small size." R. Juda in the name of Rab said: "Never shall a man absent himself from the house of learning, not even for a while; for the above Mishnah (regarding a ship of the Jordan) had been taught at the house of study for many years, and not one knew the reason for it, until R. Chanina b. Akabia came and explained it." R. Jonathan said: "Never shall a man absent himself from the house of learning and of learned words, even though he be at the point of death; for it is said (Num. 19, 14.) This is the Torah, when a man dieth in a tent, i.e., even at the point of death shall a man study the Torah." Resh Lakish said: "The words of the Torah will not endure except with him who is ready to die for it; as it is written. This is the law, when a man dieth in a tent."
