'Unless' in the Bible

Then He said to Jacob, “Let Me go, for it is daybreak.”But Jacob said, “I will not let You go unless You bless me.”

This is how you will be tested: As surely as Pharaoh lives, you will not leave this place unless your youngest brother comes here.

But Judah said to him, “The man specifically warned us: ‘You will not see me again unless your brother is with you.’

But if you will not send him, we will not go, for the man said to us, ‘You will not see me again unless your brother is with you.’”

We told him, ‘We cannot go down unless our younger brother goes with us. So if our younger brother isn’t with us, we cannot see the man.’
