Revelation 7:16

11 And all the angels were round about the high seat, and about the rulers and the four beasts; and they went down on their faces before the high seat, and gave worship to God, saying,

12 So be it. Let blessing and glory and wisdom and praise and honour and power and strength be given to our God for ever and ever. So be it.

13 And one of the rulers made answer, saying to me, These who have on white robes, who are they, and where did they come from?

14 And I said to him, My lord, you have knowledge. And he said to me, These are they who came through the great testing, and their robes have been washed and made white in the blood of the Lamb.

15 This is why they are before the high seat of God; and they are his servants day and night in his house: and he who is seated on the high seat will be a tent over them.

16 They will never be in need of food or drink: and they will never again be troubled by the burning heat of the sun:

17 For the Lamb who is on the high seat will be their keeper and their guide to fountains of living water: and God will make glad their eyes for ever.
