'Loved' in the Bible

Moreover, because he loved your ancestors, he chose their descendants who followed them and personally brought you out of Egypt with his great power

Suppose a man has two wives, one whom he loves more than the other, and they both bear him sons, with the firstborn being the child of the less loved wife.

Rather, he must acknowledge the son of the less loved wife as firstborn and give him the double portion of all he has, for that son is the beginning of his father's procreative power -- to him should go the right of the firstborn.
