Philaret of Moscow (Drosdow)
Jacob offered his blessings to Pharaoh, which means he saluted him in accordance with the customary practices of the era.
After this Joseph brought in his father to the king, and presented him before him: and he blessed him.
וַיָּבֵ֤א יוֹסֵף֙ אֶת־יַֽעֲקֹ֣ב אָבִ֔יו וַיַּֽעֲמִדֵ֖הוּ לִפְנֵ֣י פַרְעֹ֑ה וַיְבָ֥רֶךְ יַעֲקֹ֖ב אֶת־פַּרְעֹֽה׃
