'Unless' in the Bible

how he entered into the house of God, in the section of Abiathar the high priest, and ate the shew-bread, which it is not lawful unless for the priests to eat, and gave even to those that were with him?

“On the other hand, no one can enter a strong man’s house and rob his possessions unless he first ties up the strong man. Then he will rob his house.

(For the Pharisees, in fact all the Jews, will not eat unless they wash their hands ritually, keeping the tradition of the elders.

When they come from the marketplace, they do not eat unless they have washed. And there are many other customs they have received and keep, like the washing of cups, jugs, copper utensils, and dining couches.)

And as they descended from the mountain, he charged them that they should relate to no one what they had seen, unless when the Son of man should be risen from among the dead.

Unless the Lord limited those days, no one would survive. But He limited those days because of the elect, whom He chose.
