'Tomorrow' in the Bible

Then Jezebel sent a messenger to Elijah, saying, "So let the gods do to me, and more also, if I don't make your life as the life of one of them by tomorrow about this time!"

but I will send my servants to you tomorrow about this time, and they shall search your house, and the houses of your servants; and it shall be, that whatever is pleasant in your eyes, they shall put it in their hand, and take it away."'"
