“bless the lads.” The verb is singular. This has caused some theologians to say that God is a Trinity because here God and the angel are spoken of with a singular verb, “bless.” But there is much wrong with that logic. For one thing, it occurs a number of times in the Bible that a plural subject is paired with a singular verb (cp. Exod. 4:29 (“went”); Exod. 8:8; 10:3; Josh. 8:3; etc.). Also, in this case, the angel may have been representing God in this context, as angels often do; there is no “and” before “the angel,” so the angel could be representing God, and this would be a case of divine agency. That would make this verse about the representative of God, just like the angel who wrestled with Jacob and changed his name to Israel.
