וַיֵּצֵ֤א הָרִאשׁוֹן֙ אַדְמוֹנִ֔י כֻּלּ֖וֹ כְּאַדֶּ֣רֶת שֵׂעָ֑ר וַיִּקְרְא֥וּ שְׁמ֖וֹ עֵשָֽׂו׃
Und der erste kam heraus, rötlich, am ganzen Körper wie ein härener Mantel, und sie nannten ihn Esau (Esav.)
Targum Jonathan on Genesis
And the first came forth wholly red, as a garment of hair: and they called his name Esau, because he was born altogether complete, with the hair of the head, and the beard, and teeth, and grinders.
Targum Jerusalem
And the first came forth wholly red, as a garment of hair: and they called his name Esau.
