Revelation 7:13-15

Darby Translation

¹³ And one of the elders answered, saying to me, These who are clothed with white robes, who are they, and whence came they?

¹⁴ And 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.

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