'Rising' in the Bible

and I saw another messenger going up from the rising of the sun, having a seal of the living God, and he did cry with a great voice to the four messengers, to whom it was given to injure the land and the sea, saying,

And the sixth messenger did pour out his vial upon the great river, the Euphrates, and dried up was its water, that the way of the kings who are from the rising of the sun may be made ready;

and the rest of the dead did not live again till the thousand years may be finished; this is the first rising again.

Happy and holy is he who is having part in the first rising again; over these the second death hath not authority, but they shall be priests of God and of the Christ, and shall reign with him a thousand years.
