'Stronger' in the Bible

And Jehovah said unto her, Two nations are in thy womb, And two peoples shall be separated from thy bowels. And the one people shall be stronger than the other people. And the elder shall serve the younger.

And it came to pass, whensoever the stronger of the flock did conceive, that Jacob laid the rods before the eyes of the flock in the gutters, that they might conceive among the rods;

but when the flock were feeble, he put them not in: so the feebler were Laban's, and the stronger Jacob's.
