Genesis 46:1
JPS-1917וַיִּסַּ֤ע יִשְׂרָאֵל֙ וְכׇל־אֲשֶׁר־ל֔וֹ וַיָּבֹ֖א בְּאֵ֣רָה שָּׁ֑בַע וַיִּזְבַּ֣ח זְבָחִ֔ים לֵאלֹהֵ֖י אָבִ֥יו יִצְחָֽק׃
And Israel took his journey with all that he had, and came to Beer-sheba, and offered sacrifices unto the God of his father Isaac.
Rashi Commentary
The suffix ה replaces the prefix ל locale (Yevamot 13b). לאלהי אביו יצחק TO THE GOD OF HIS FATHER, ISAAC — The duty of honouring one’s father is more imperative than that of honouring one’s grandfather (Genesis Rabbah 94:5); therefore the sacrifices are associated with the name of Isaac and not with that of Abraham.
