Five-fold Reference to the Devil:

2. … “And the great dragon was cast out, that old serpent, called the Devil, and Satan, which deceiveth the whole world: he was cast out into the earth, and his angels were cast out with him.” (Rev. 12:9). (Emphasis added).
3. … “Therefore rejoice, ye heavens, and ye that dwell in them. Woe to the inhabiters of the earth and of the sea! for the devil is come down unto you, having great wrath, because he knoweth that he hath but a short time.” (Rev. 12:12). (Emphasis added).

Commentary: Three lowercase (d)evil, two uppercase (D)evil. The distinction is important. When the term is capitalized, it refers to a name or title. Devil (capitalized twice) is the name of the evil one, devil (lower case, three times) is a descriptive reference to the evil one. D(d)evil is the only term that is used interchangeably as a name and also as a descriptive reference. God’s word is so precise, logical and mathematically arranged that even the use of capitalization and the sequencing of a name/description has meaning within meaning. In the use of the word ‘D(d)evil’; the first instance of it being used is in Rev. 2:10 and is not capitalized and is represented with a small ‘d’. Every following instance of this word alternates between the capital ‘D’ and the lowercase ‘d’, as such; d – D –d – D – d.  When referencing the evil one, the Word of God alternates, in exact sequence, to the name of the evil one and a description of the evil one. Consider the ordering or context describing the evil one. He is described as casting individual Christians into prison, next he is described as deceiving nations, next he is kicked out of heaven and has great wrath, then he is bound in prison for 1,000 years, lastly he is cast into the lake of fire and brimstone. These verses quickly summarize the actions and results of the angel once known as Lucifer. God is in control and through the word of His Holy Spirit, informs us that Satan/Devil will end up in the lake of fire and brimstone.
