Ambrose of Milan, on Gen 49:22

“Joseph is a growing son, a growing son and comely to behold; the daughters run to and fro upon the wall.”

“What was the reason that, above all his sons, the father pursued Joseph more abundantly as his son, if not because he already saw in him the mysteries of Christ prefigured? Therefore, blessing him more who was expected than him who was seen, he said: Joseph, my son, is to be multiplied. Who is to be multiplied, if not Christ, whose grace is always increased, and whose glory has no end? Concerning whom also John says: He must increase, but I must decrease; for through his name, which is salvation and perfection, grace has been multiplied and abounded in this world. My son is to be enlarged; and therefore, because his brothers saw him growing, they began to envy. But Joseph understood and zeal entered into those whom he favored the most. Finally, he said: I came not but for the lost sheep of the house of Israel. And they said: We do not know where he is from. He cared for them, and they denied him.”
