Midrasz do Jeremiasza 8:16

(Gen. 14, 15) And he divided himself against them, he and his servants by night (Lyelah) and smote them. R. Jochanan said: "The name of the angel who came to assist Abraham was Lyelah (night) as it is said (Job 3, 3) And the night when it was said, There hath been a male child conceived, etc." R. Isaac of Nafha said: "This means a thing concerning the night was wrought for him, as it is said (Jud. 5, 20) From heaven they fought — the stars in their courses fought against Sissera." Resh Lakish remarked: "The explanation of Nafcha is better than that of bar Nafcha's" (Jochanan, who was called bar Nafcha). R. Jochanan said: "When that righteous man (Abraham) reached the city of Dan, his strength began to fail, for [he saw that] in the future his children would worship idols in Dan, it it is said (I Kin. 12, 29) And the other he put in Dan. And also this wicked one Sennacherib did not feel himself strong until he reached Dan, as it is said (Jer. 8, 16) From Dan was heard the snorting of his horses."
