'End' in the Bible

He who overcomes, and he who keeps my works to the end, to him I will give authority over the nations.

He said to me, "It is done! I am the Alpha and the Omega, the Beginning and the End. I will give freely to him who is thirsty from the spring of the water of life.

I am the Alpha and the Omega, the First and the Last, the Beginning and the End.
