וְלֹ֣א הִכִּיר֔וֹ כִּֽי־הָי֣וּ יָדָ֗יו כִּידֵ֛י עֵשָׂ֥ו אָחִ֖יו שְׂעִרֹ֑ת וַֽיְבָרְכֵֽהוּ׃
Y no le conoció, porque sus manos eran vellosas como las manos de Esaú: y le bendijo.
Targum Jonathan on Genesis
But he recognised him not, because his hands were hairy as the hands of Esau his brother, and he blessed him.
