Charles Ellicott Commentary Genesis 49:25

"Even by the God of thy father, who shall help thee, And by the Almighty, who shall bless thee, With blessings of heaven above, Blessings of the deep that coucheth beneath, Blessings of the breasts, and of the womb." — Genesis 49:25 (ASV)

Even by the God of thy father. —In the Hebrew this follows directly upon the preceding clause: “from the Shepherd, the Stone of Israel; from the God of thy father, who shall help thee; and from the Almighty,” etc.

Blessings of heaven above are the rains and dew; those of “the deep” beneath are lakes, rivers, and springs; and those of “the breasts and womb” mean an abundant offspring both of men and cattle. (For the opposite curse see Hosea 9:14.)
