'It is Impossible' in the Bible

And Jesus said unto them - Is it possible for the sons of the bridechamber, while the bridegroom is with them, to be fasting? So long as they have the bridegroom with them, it is impossible, to fast.

if a family be divided against it self, it is impossible for it to subsist.

Jesus looking upon them saith, With men it is impossible, but not with God: for all things are possible with God.
