'Possible' in the Bible

And the other wife did everything possible to make her unhappy, because the Lord had not let her have children;

And Samuel said, How is it possible for me to go? If Saul gets news of it he will put me to death. And the Lord said, Take a young cow with you and say, I have come to make an offering to the Lord.

And David took Saul's sword and put the band round him over the metal coat, and was unable to go forward; for he was not used to them. Then David said to Saul, It is not possible for me to go out with these, for I am not used to them. So David took them off.

And Saul and his men went on one side of the mountain, and David and his men went on the other: and David's purpose was to get away as quickly as possible, for fear of Saul; for Saul and his men were making a circle round David and his men in order to take them.

So now, give thought to what you are going to do; for evil is in store for our master and all his house: for he is such a good-for-nothing person that it is not possible to say anything to him.
