Bible Notes Online - Revelation 8 - ESV
Commentary

v1: The seventh seal brought a half hour of silence. There is a similar pause after the sixth trumpet (10.7). This is quite striking, since Heaven is generally described as a place of sound. 'What we cannot speak about we must pass over in silence.' (Zimbabwean proverb) The human mind will try to unwrap and explain all the details of Revelation. This period of silence tells us to stand still and wonder at the greatness of God (Job 37.14).

v2-5: As God's wrath is poured out on the earth, we see control and order, not the uncontrolled unrestrained anger of a man, but the proper response of the holy God towards those who refuse to believe and to obey Him.

There are the prayers of the saints; this must include the prayers of those slain for their testimony (6.10). The prayers are offered as incense, but fire from the altar is thrown down to the earth.

This silence ends as the angels take the seven trumpets, which are described in chapters 9-11.

v7-13: The first four angels bring widespread but again restricted judgments upon the earth; in each case, one third only is affected. God's wrath remains controlled. It is still a serious matter to fall into the hands of God; "Woe! Woe! Woe! to the inhabitants of the earth!" This statement introduces the three "woes" which fall on the earth and its people.

The later trumpets are much worse than these first four.
