Continuing from chapter 8 we see two more of the 7 trumpets sounded which bring them hordes of Saracen (Arab) and Turkish armies to invade the Eastern part of the old Roman Empire, called the Byzantine Empire, as well as north Africa and the middle Eastern areas. The historical interpretation is continued and covers the period of history of 476 AD (the fall of Western Rome) to 1453 AD (the fall of Constantinople in the Christian Eastern Roman Byzantine Empire). This chapter divides in to 3 segments, v. 1-12, v. 13-19 and v. 20,21.
Fifth trumpet (v.1) – a star fell from heaven, meaning an angel to whom was given the key to the bottomless pit or Hell.
A star fallen from heaven (v.1) symbolises the fall of a prince or a leader, who fell to Earth meaning he has influence in the earthly realm. He was given power to unleash hellish influences on Earth. It sounds much like Satan who was cast out of heaven (Revelation 12:9), and given limited power by God on Earth. Some commentators mark him as Muhammad. Now Muhammad lived from 570 AD to 632 AD. Most of this suggested period, ending in 632 AD, for an invading Saracen (Arabian) army, would predate his life.
From the 3rd century AD, Arabian history becomes more tangible with the rise of the Ḥimyarite, and with the appearance of the Qaḥṭānites in the Levant and the gradual assimilation of the Nabataeans by the Qaḥṭānites in the early centuries, a pattern of expansion exceeded in the explosive Muslim conquests of the 7th century. For this leader to be Muhammad it would have to be that most of the conquests it represents occurred in the period, not leading up to 632 AD, but after 632 AD, for a period of 150 years (v.5,10; 5 months = 150 ‘days’ = 150 years) when Arab Islam assaulted the old Roman world.
The ‘air was darkened by reason of the smoke from the pit’ (v.2) symbolises these hellish influence. A great horde of ‘locusts’ (v.3) symbolising great destroying armies ‘came out of the smoke’ and they we sent to torment (v.4,5) those humans who did not have the salvation of our God, where salvation is symbolised by a seal in their foreheads.
