After this I looked and saw a door standing open in heaven. And the voice I had previously heard speak to me like a trumpet was saying, “Come up here, and I will show you what must happen after these things.”
KJV
After this I looked, and, behold, a door [was] opened in heaven: and the first voice which I heard [was] as it were of a trumpet talking with me; which said, Come up hither, and I will shew thee things which must be hereafter.
ASV
After these things I saw, and behold, a door opened in heaven, and the first voice that I heard, a voice as of a trumpet speaking with me, one saying, Come up hither, and I will show thee the things which must come to pass hereafter.
