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 lieth under, blessings of the breasts, and of the womb:

Blessings of heaven above - i:e., copious descents of rain and dew, which are so necessary for promoting the growth of vegetation (Leviticus 26:4; Deuteronomy 28:12; Deuteronomy 33:14).

Blessings of the deep that lieth under - i:e., springs and rivers in the earth, which contribute to moisten and fertilize the soil х taachat (H8478) is here used adverbially for 'beneath'].

Blessings of the breasts and of the womb - i:e., a numerous and healthy progeny of descendants, as well as of cattle.
