Why does the Torah tell us in verse 26.12 of B’rashith (Genesis), “And Isaac sowed in that land, and found in the same year a hundredfold; and the LORD blessed him;” while in verse 13 Isaac is only referred to as the man? That is, why is he not mentioned by name in verse 13? 13 “And the man waxed great, and grew more and more until he became very great.”
It is only when Isaac becomes identified as a man of greatness, that is, in verse 26.16 mightier than the Philistines and having the upper hand in making a covenant – Abimilech came to Isaac, not the other way around (26.26) (to ensure that Isaac would not join with the enemies of the Philistines) that we see him identified both by HaShem (verse 12) and his neighbors (verse 29) as Blessed of HaShem!
His greatness is in addition to his wealth. He is identified as a great man because he is able to make peace with his neighbors. Until he is recognized as “Blessed of HaShem,” he is not a man of greatness and is not able to make peace with his neighbors.
