'End' in the Bible

“I am the Alpha and the Omega [the Beginning and the End],” says the Lord God, “Who is [existing forever] and Who was [continually existing in the past] and Who is to come, the Almighty [the Omnipotent, the Ruler of all].”

And he who overcomes [the world through believing that Jesus is the Son of God] and he who keeps My deeds [doing things that please Me] until the [very] end, to him I will give authority and power over the nations;

and the angel hurled him into the abyss, and closed it and sealed it above him [preventing his escape or rescue], so that he would no longer deceive and seduce the nations, until the thousand years were at an end. After these things he must be liberated for a short time.

And He said to me, “It is done. I am the Alpha and the Omega, the Beginning and the End. To the one who thirsts I will give [water] from the fountain of the water of life without cost.

I am the Alpha and the Omega, the First and the Last, the Beginning and the End [the Eternal One].”
