John Calvin on Genesis 9:26

26. Blessed be the Lord God of Shem . Noah blesses his other children, but in a different manner. For he places Shem in the highest post of honor. And this is the reason why Noah, in blessing him, breaks forth in the praise of God, without adhering to the person of man. For the Hebrews, when they are speaking of any rare and transcendent excellence, raise their thoughts to God. Therefore the holy man, when he perceived that the most abundant grace of God was destined for his son Shem, rises to thanksgiving. Whence we infer, that he spoke, not from carnal reason, but rather treated of the secret favors of God, the result of which was to be deferred to a remote period. Finally, by these words it is declared, that the benediction of Shem would be divine or heavenly.
