Romans 9:10-12

And not only that, but this too: Rebekah conceived twin sons by one man [under the same circumstances], by our father Isaac; and though the twins were not yet born and had not done anything either good or bad, so that God’s purpose [His choice, His election] would stand, not because of works [done by either child], but because of [the plan of] Him who calls them, it was said to her, “THE OLDER (Esau) WILL SERVE THE YOUNGER (Jacob).” [Gen 25:21-23]
