'Endure' in the Bible

But he has no root in himself and does not endure; when trouble or persecution comes because of the word, immediately he falls away.

Jesus answered, "You unbelieving and perverse generation! How much longer must I be with you? How much longer must I endure you? Bring him here to me."

But he that shall endure unto the end, the same shall be saved.

And if those days [of tribulation] had not been cut short, no human life would be saved; but for the sake of the elect (God’s chosen ones) those days will be shortened.
