Revelation 8:1 - Wesley's Explanatory Notes

And when he had opened the seventh seal, there was silence in heaven — Such a silence is mentioned but in this one place. It was uncommon, and highly observable: for praise is sounding in heaven day and night. In particular, immediately before this silence, all the angels, and before them the innumerable multitude, had been crying with a loud voice; and now all is still at once: there is an universal pause. Hereby the seventh seal is very remarkably distinguished from the six preceding. This silence before God shows that those who were round about him were expecting, with the deepest reverence, the great things which the Divine Majesty would farther open and order. Immediately after, the seven trumpets are heard, and a sound more august than ever. Silence is only a preparation: the grand point is, the sounding the trumpets to the praise of God. About half an hour — To St. John, in the vision, it might seem a common half hour.
