The miraculous deliverance of Abraham from the fiery furnace, together with his later fortunes, was the fulfilment and explanation of what his father Terah had read in the stars. He had seen the star of Haran consumed by fire, and at the same time fill and rule the whole world. The meaning was plain now. Haran was irresolute in his faith, he could not decide whether to adhere to Abraham or the idolaters.
When it befell that those who would not serve idols were cast into the fiery furnace, Haran reasoned in this manner: "Abraham, being my elder, will be called upon before me. If he comes forth out of the fiery trial triumphant, I will declare my allegiance to him; otherwise I will take sides against him." After God Himself had rescued Abraham from death, and Haran's turn came to make his confession of faith, he announced his adherence to Abraham.
But scarcely had he come near the furnace, when he was seized by the flames and consumed, because he was lacking in firm faith in God. Terah had read the stars well, it now appeared: Haran was burnt, and his daughter Sarah became the wife of Abraham, whose descendants fill the earth. In another way the death of Haran was noteworthy. It was the first instance, since the creation of the world, of a son's dying while his father was still alive.
