Que aconteça que a jovem à qual eu disser: 'Por favor, inclina o teu cântaro para que eu beba', e ela responder: 'Bebe, e também darei de beber aos teus camelos' — seja ela a que Tu designaste para o Teu servo Yitzchak; e por isso saberei que mostraste bondade ao meu senhor."
Derashot HaRan
And if one would ask: if one is forbidden to resort to these signs and is called an augurer if he does so, how are we to understand (Chullin 95b): "Rav would test [propitiousness] by means of a ferry" [if it came towards him, he would see it as a propitious sign]. What difference is there between a ferry and a deer crossing one's path? — the answer is: though Rav tested propitiousness by means of a ferry, he did not make his future action entirely dependent upon the result of that test, but only sought some indication of whether he would meet with success; and even if the sign was that he would not, he would not, because of this, abandon his undertaking, knowing as he did that the Blessed One can change everything according to His will. Augury is forbidden only to him who relies upon it implicitly, as is made clear there (Ibid): "And even so [even though the meat in question had been under constant surveillance], Rav did not eat of that meat. Why not, if it had been under constant surveillance? It must be because he had [unlawfully] resorted to augury [and therefore banned to himself the fruits, as it were, of that augury]. But did not Rav himself say that any augurer who is not like Eliezer the servant of Abraham and Jonathan the son of Saul is not an augurer?" That is: if he does not rely implicitly upon his augury as did Eliezer the servant of Abraham, who said (Genesis 24:14): "And it will be that maiden to whom I say: 'Hand down your pitcher that I may drink' — and who answers: 'Drink, and I will also give your camels to drink' — she is the one whom You have designated for your servant Isaac," and as Jonathan the son of Saul, who said (I Samuel 14:10): "And if they say thus: 'Come up to us' — then we shall go up, for the L-rd has given them into our hand" — if one does not rely implicitly upon his augury as these did, then he is not considered an augurer. And Rav did not rely implicitly upon his augury but only said: "A ferry is coming towards me — it is a good day for wayfarers." He did not say that if a ferry came towards him he would go, and that if it did not, he would not.
