'Stronger' in the Bible

And Yahweh said to her, "Two nations [are] in your womb, and two peoples {from birth} shall be divided. And {one people shall be stronger than the other}. And [the] elder shall serve [the] younger."

And whenever any of the stronger of the flocks were in heat, Jacob put the branches {in full view} of the flock in the troughs that they might mate among the branches.

But with the more feeble of the flock he would not put [them there]. So the feebler were Laban's and the stronger [were] Jacob's.
