'End' in the Bible

And the one who conquers and who keeps my works until the end, I will give him authority over the nations,

And he said to me, "It is done! I [am] the Alpha and the Omega, the beginning and the end. To the one who is thirsty I will give [water] from the spring of the water of life freely.

I [am] the Alpha and the Omega, the first and the last, the beginning and the end."
