Jacob blessed Pharaoh— When the word, bless, says Calmet, is applied to God, it signifies to thank, or praise; when to men, it signifies, to wish them health, prosperity, or happiness: in which latter sense it is here used. Jacob blessed Pharaoh, i.e.. wished him health, and a long and happy reign, in gratitude for the protection with which he had honoured him and his family; and probably he did this in the name of the God of his fathers. The common salutation among the Jews, O king, live for ever! was of this same kind.
