Revelation 7:14-15

14And I said to him, My lord, thou knowest. And he said to me, These are they who come out of the great tribulation, and have washed their robes, and have made them white in the blood of the Lamb.

15Therefore are they before the throne of 1God, and serve him day and night in his temple, and he that sits upon the throne shall spread his tabernacle over them.
