Revelation 4:1

New Matthew Bible

He sees heaven open, and the seat, and one sitting upon it, and 24 seats around it with 24 elders sitting upon them, and four creatures praising God day and night.

4 After this I looked, and behold, a door was open in heaven, and the first voice that I heard was as it were of a trumpet talking with me, which said, Come up here, and I will show you things that must be fulfilled hereafter.
