ISB ~ Revelation 8 v1

silence in heaven:Recalls the liturgical silence that fell over the Jerusalem Temple when the priests offered incense and the multitudes prayed quietly in the outer courts (Lk 1:810). Jewish tradition also speaks of an angelic silence in the heaven when Israel prays and when the judgments of God are about to fall (Hab 2:20; Zeph 1:7). Here an angel offers the prayers of the saints with incense (Rev 8:3-4) just before curses descend upon the earth (8:7-9:21; 11:15-19).
