'Unless' in the Bible

But no one can go into a strong man’s house and steal his property unless he first overpowers and ties up the strong man, and then he will ransack and rob his house.

(For the Pharisees and all of the Jews do not eat unless they carefully wash their hands, holding firmly to the traditions of the elders;

and when they come from the market place, they do not eat unless they cleanse themselves [completely according to ritual]; and there are many other things [oral, man-made laws and traditions handed down to them] which they follow diligently, such as the washing of cups and pitchers and copper utensils.)

And if the Lord had not shortened the days, no human life would have been saved; but for the sake of the elect, whom He chose [for Himself], He shortened the days.
