Genesis 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”.

וַיֹּ֤אמֶר אֵלָיו֙ לָבָ֔ן אִם־נָ֛א מָצָ֥אתִי חֵ֖ן בְּעֵינֶ֑יךָ נִחַ֕שְׁתִּי וַיְבָרְכֵ֥נִי יְהֹוָ֖ה בִּגְלָלֶֽךָ׃

And Lavan said to him, I pray thee, if I have found favour in thine eyes, I have learned by signs that the Lord has blessed me for thy sake.
