'Tomorrow' in the Bible

Then Jezebel sent a messenger to Elijah, saying, “So may the gods do to me, and even more, if by this time tomorrow I do not make your life like the life of one of them.”

but about this time tomorrow I will send my servants to you, and they will search your house and the houses of your servants; and they will take with their hands (confiscate) whatever is desirable in your eyes and carry it away.’”
