Sforno on Genesis 48:5/ספורנו על בראשית מ״ח:ה׳

1ועתה שני בניך הנולדים לך....לי הם, G’d gave me only these two sons of yours together with you. Yaakov had confirmed his meaning when he said that just as he had not expected to see Joseph again he had also not expected to live to see two of his sons. (verse 11)
