וַתֵּ֡לֶד שָׂרָה֩ אֵ֨שֶׁת אֲדֹנִ֥י בֵן֙ לַֽאדֹנִ֔י אַחֲרֵ֖י זִקְנָתָ֑הּ וַיִּתֶּן־לּ֖וֹ אֶת־כָּל־אֲשֶׁר־לֽוֹ׃
Y Sara, mujer de mi amo, parió en su vejez un hijo á mi señor, quien le ha dado todo cuanto tiene.

Chizkuni
אחרי זקנתה, “after she had become old;” so that he could not expect to have any more sons from her.
