'Reason' in the Bible

But now that the child is dead there is no reason for me to go without food; am I able to make him come back to life? I will go to him, but he will never come back to me.

Then Absalom said, If you will not go, then let my brother Amnon go with us. And the king said to him, Is there any reason for him to go with you?

And David said to Ziba, What is your reason for this? And Ziba said, The asses are for the use of the king's people, and the bread and the fruit are food for the young men; and the wine is for drink for those who are overcome by weariness in the waste land.
