וַיְהִ֤י יִצְחָק֙ בֶּן־אַרְבָּעִ֣ים שָׁנָ֔ה בְּקַחְתּ֣וֹ אֶת־רִבְקָ֗ה בַּת־בְּתוּאֵל֙ הָֽאֲרַמִּ֔י מִפַּדַּ֖ן אֲרָ֑ם אֲח֛וֹת לָבָ֥ן הָאֲרַמִּ֖י ל֥וֹ לְאִשָּֽׁה׃
Ishak berumur empat puluh tahun ketika ia mengambil Ribka, anak Betuel, orang Aram dari Padan-Aram, saudara perempuan Laban, orang Aram itu, menjadi istrinya.
Shenei Luchot HaBerit
ויהי יצחק בן ארבעים שנה בקחתו את רבקה. Rashi comments on this verse that Abraham on his return from Mount Moriah heard of Rebeccah's birth. Isaac was 37 years old at the time,etc. Why did Rashi have to inform us of these facts? They are spelled out in the Torah!
