'Unless' in the Bible

And he said to him, "Far from it! You will not die! Look, my father does not do {anything large or small unless he reveals it to me}. Why should my father hide this thing or anything from me?"

And yet, Jehovah liveth, God of Israel, who hath kept me back from doing evil with thee, for unless thou hadst hasted, and dost come to meet me, surely there had not been left to Nabal till the light of the morning, of those sitting on the wall.'
