Kommentar zu Bereschit 30:27

נחשתי I HAVE DIVINED — He was a diviner. “I have discovered by my art of divination that through you a blessing has come to me. When you first came here I had no sons” — for it is said (29:6) “And, behold, Rachel his daughter is coming with the flock”: is it possible if he had sons that he would have let his daughter go among the shepherds ? — now, however, he had sons, as it is said (31:1) “And he heard the words of Laban’s sons”.

‘NICHASHTI’ I HAVE OBSERVED THE SIGNS AND THE ETERNAL HATH BLESSED ME FOR THY SAKE. That is, “on account of you and your merit for you are a righteous man.” The word nichashti means “I have tested,” and every form of nichesh connotes testing. And some say¹⁵²Ibn Ezra. that Laban was a diviner with teraphim.¹⁵³See Ramban further, 31:19.
Jacob, however, said, And the Eternal hath blessed thee ‘leragli’ (since my coming),¹⁵⁴Verse 30 here. but, in a humble manner, he did not want to say “for my sake.” Thus, he said leragli, meaning that “from the time I set my foot in your house, you have been blessed.”

אם נא מצאתי חן בעיניך, if you love me at all, as would be appropriate for people of the same flesh and blood. It is not proper for you to abandon me at this stage. Why would he term Yaakov’s leaving for his own home as abandoning Lavan? נחשתי, I am absolutely convinced that my good fortune during the last 14 years commenced with your arrival at my doorstep. As the Talmud Berachot 42 puts it:תכף לתלמיד חכם ברכה, attaching oneself to a Torah scholar and playing host to him results in the host receiving Divine blessings. [the Talmud quotes our verse as its source. Ed.]
