'Done' in the Bible

And the seventh poured out his bowl on the air; and there came out a great voice from the temple of the heaven, from the throne, saying, It is done.

And I saw thrones; and they sat upon them, and judgment was given to them; and the souls of those beheaded on account of the testimony of Jesus, and on account of the word of God; and those who had not done homage to the beast nor to his image, and had not received the mark on their forehead and hand; and they lived and reigned with the Christ a thousand years:

And he said to me, It is done. I am the Alpha and the Omega, the beginning and the end. I will give to him that thirsts of the fountain of the water of life freely.
