Genesis 48:19
19His father refused, and said, “I know, my son, I know. He also will become a people, and he also will be great. However, his younger brother will be greater than he, and his offspring will become a multitude of nations.”
Arminian
“I know, my son, I know.” Manasseh will be a people and great; Ephraim greater still. Wesley: God often gives most to those least likely.
Clarke keeps the balance: temporal and national preferment may rest in secret counsel; that differs from saying converting grace is withheld from some by an arbitrary shut door. Both boys are blessed; the difference is degree of public greatness.
Reformed
He refuses. Calvin: Jacob does not weigh worth; he pronounces what God decreed. Dignity is hidden in God’s counsel until vocation makes it plain.
Seeking other cisterns for adoption’s cause is vain. The primary source of election is God’s free good pleasure—and Manasseh is still called great, so envy is forbidden.
