'Reason' in the Bible

But, for this very reason, I have kept you from destruction, to make clear to you my power, and so that my name may be honoured through all the earth.

And when your children say to you, What is the reason of this act of worship?

And when your son says to you in time to come, What is the reason for this? say to him, By the strength of his hand the Lord took us out of Egypt, out of the prison-house:

For in six days the Lord made heaven and earth, and the sea, and everything in them, and he took his rest on the seventh day: for this reason the Lord has given his blessing to the seventh day and made it holy.
