'Unless' in the Bible

Then He said, “Let Me go, for day is breaking.” But Jacob said, “I will not let You go unless You declare a blessing on me.”

In this way you shall be tested: by the life of Pharaoh, you shall not leave this place unless your youngest brother comes here!

But Judah said to him, “The man [representing Pharaoh] solemnly and sternly warned us, saying, ‘You will not see my face [again] unless your brother is with you.’

But if you will not send him, we will not go down there; for the man said to us, ‘You will not see my face unless your brother is with you.’”

You said to your servants, ‘Unless your youngest brother comes with you, you shall not see my face again.’
