Ambrose of Milan, on Gen 49:1

“And Jacob called his sons, and said to them: Gather yourselves together that I may tell you the things that shall befall you in the last days.”

“After this blessing was celebrated, he also called his sons (Gen. XLIX, 1). And the one who had preferred the younger to the elder began with the first, so that he might bestow favor upon him in that mystery, and observe the order of age in this. At the same time, he who had previously blessed them both, along with all their posterity and future offspring, lest the repeated blessing of the people should appear superfluous, or the former be considered weak, rightly declares that he is repeating more of an announcement of things that would happen in later times, rather than conferring a blessing.”
