Matthew Henry on Genesis 48:8–end
Here is, I. The blessing with which Jacob blessed the two sons of Joseph, which is the more remarkable because the apostle makes such particular mention of it (Heb 11:21), while he says nothing of the blessing which Jacob pronounced on the rest of his sons, though that also was done in faith.

and he brought them near unto him; that he might have a better sight of them and bless them:
and he kissed them, and embraced them: as a token of his affection for them.
