'Unless' in the Bible

Unless the God of my father, the God of Abraham, and the fear of Isaac, had been with me, surely now you would have sent me away empty. God has seen my affliction and the labor of my hands, and rebuked you last night."

The man said, "Let me go, for the day breaks." Jacob said, "I won't let you go, unless you bless me."

By this you shall be tested. By the life of Pharaoh, you shall not go forth from here, unless your youngest brother comes here.

Judah spoke to him, saying, "The man solemnly warned us, saying, 'You shall not see my face, unless your brother is with you.'

but if you'll not send him, we'll not go down, for the man said to us, 'You shall not see my face, unless your brother is with you.'"

You said to your servants, 'Unless your youngest brother comes down with you, you will see my face no more.'

We said, 'We can't go down. If our youngest brother is with us, then we will go down: for we may not see the man's face, unless our youngest brother is with us.'
