וַיְהִ֗י אַחֲרֵי֙ מ֣וֹת אַבְרָהָ֔ם וַיְבָ֥רֶךְ אֱלֹהִ֖ים אֶת־יִצְחָ֣ק בְּנ֑וֹ וַיֵּ֣שֶׁב יִצְחָ֔ק עִם־בְּאֵ֥ר לַחַ֖י רֹאִֽי׃ (ס)
And it came to pass after the death of Abraham, that God blessed Isaac his son; and Isaac dwelt by Beer-lahai-roi.
Targum Jonathan on Genesis
And because Abraham had not designed to bless Ishmael, therefore he blessed not Izhak; for had he blessed Izhak and not Ishmael, it would have kept them in enmity. But, after the death of Abraham, the Lord blessed Izhak; and Izhak dwelt near the well at which was revealed the glory of the Living and Eternal One, who seeth and is not seen.
