15 If a man has two wives, and he loves one but not the other, and both bear him sons but the firstborn is the son of the wife he does not love,
15 If a man have two wives, one beloved, and another hated, and they have born him children, both the beloved and the hated; and if the firstborn son be hers that was hated:
15 "If a man has two wives, the one loved and the other unloved, and both the loved and the unloved have borne him children, and if the firstborn son belongs to the unloved,
15 When a man has two wives, one loved and the other hated, and they both give him sons, but the firstborn is from the hated wife,
15 "If a man has two wives, one loved and the other unloved, and they have borne him children, both the loved and the unloved, and if the firstborn son is of her who is unloved,
15 "Suppose a man has two wives, but he loves one and not the other, and both have given him sons. And suppose the firstborn son is the son of the wife he does not love.
