'Promise' in the Bible

Wherever you die, I will die -- and there I will be buried. May the Lord punish me severely if I do not keep my promise! Only death will be able to separate me from you!"

Remain here tonight. Then in the morning, if he agrees to marry you, fine, let him do so. But if he does not want to do so, I promise, as surely as the Lord lives, to marry you. Sleep here until morning."
