'Remain' in the Bible

Do not be afraid of the things you are about to suffer. The devil is about to have some of you thrown into prison so you may be tested, and you will experience suffering for ten days. Remain faithful even to the point of death, and I will give you the crown that is life itself.

Be watchful, and strengthen the things which remain, that are ready to die: for I have not found thy works perfect before God.

They are also seven kings: Five have fallen, one is, the other has not yet come, and when he comes, he must remain for a little while.
