The 'vile person' of Daniel 11:21 is the coming Antichrist.
Les Feldick identifies this individual with the end-time world ruler Daniel calls the Antichrist. This ruler will come on the scene with peace and prosperity, gaining power through flattery and political manipulation rather than military force. Historical figures like Antiochus the Great and Antiochus Epiphanes are types or pictures, but the final fulfillment is the coming Antichrist.
Daniel 11:21 — This is the verse the question asks about; it is the direct Bible description of the vile person.
Daniel 11:21 introduces a 'vile person' who stands up in the estate of the previous ruler. The verse says this ruler is not given the honour of the kingdom, but 'he shall come in peaceably, and obtain the kingdom by flatteries.' Scripture therefore identifies both the character and the method of this ruler: he gains power without public honor, and his accession is described in terms of flattery and intrigue rather than military conquest. In Daniel 9:27, a related 'prince that shall come' confirms a covenant with many for one week, the same seven-year period associated with the end-time ruler.
Les Feldick explicitly identifies the vile person with the Antichrist, calling him 'this Prince that shall come, this Antichrist, this vile person, this King of fierce countenance.' He teaches that the same descriptive words connected to Antiochus the Great also describe the coming man of sin, making Antiochus a type or picture of the Antichrist. Les says the Antichrist will come on the scene with a charismatic personality, promising peace and prosperity, and will sign a seven-year covenant with the nation of Israel as described in Daniel 9:27.
Daniel 11:21 describes a 'vile person' who stands up in the estate of the previous ruler. Scripture says this ruler does not receive the honour of the kingdom, but comes in peaceably and obtains the kingdom by flatteries. This is the direct biblical description of the person named in the question.
Les Feldick identifies the vile person as the Antichrist. He connects the titles from Daniel's prophecy, saying 'this Prince that shall come, this Antichrist, this vile person, this King of fierce countenance' all refer to the same end-time man. He also teaches that Antiochus the Great is a type or picture of this coming Antichrist, because the same descriptive words apply to both.
Les teaches that the Antichrist will come on the scene with flatteries and political manipulation, not with military force. He will promise everything the world and Israel are waiting to hear, including guaranteeing Israel's borders, sovereignty, and temple worship, so the world will welcome him with open arms. He will be a charismatic individual and a tremendous political manipulator, yet still an ordinary human being, born of woman and used by Satan to fulfill satanic aspirations.
Les sees the Antiochus references in Daniel as historical types, not the final fulfillment. Antiochus the Great is called a picture or type of the Antichrist because the same descriptive words are used. In another passage, Antiochus Epiphanes is also a type, having defiled the temple by sacrificing a swine on the altar. Les says the end-time Antichrist will likely do much the same thing to the temple.
Les points to Daniel 9:27 where this prince confirms a covenant with Israel for one week. He teaches that the Antichrist will make the temple desolate, even until the consummation, and that the prophetic words about the desolator will be fulfilled by this end-time ruler.
Antiochus the Great as a Type
Les says Antiochus the Great is a type or picture of the Antichrist, and the same descriptive words used for Antiochus also describe the end-time man of sin.
The Vile Person Is the Antichrist
Les explicitly calls the Antichrist 'this vile person' and says he will come with peace and prosperity, signing a seven-year covenant with Israel.
The Antichrist from Western Europe
Les places the Antichrist's final appearance out of Western Europe, where he rules for seven years before destruction.
Peace, Flattery, and Political Manipulation
Les explains that the Antichrist will come with flatteries and political manipulation rather than military force, promising Israel security and temple worship.
The Temple Desolated
Les says the temple Israel will build and use for worship will be made desolate by the end-time ruler, and the prophecy will be poured upon the desolator.
Charisma and Satanic Power
Les says the Antichrist's charisma will be so strong that the world will fall at his feet, and he will be godless, receiving his power from Satan.
Political Manipulator and Ordinary Human
Les says the Antichrist will be a flesh-and-blood human, a charismatic political manipulator used by Satan, much like Judas.
Antiochus Epiphanes as a Type
Les cites Antiochus Epiphanes' defilement of the temple with a swine sacrifice as a type of what the Antichrist will do.
Daniel 11:21: And in his estate shall stand up a vile person, to whom they shall not give the honour of the kingdom: but he shall come in peaceably, and obtain the kingdom by flatteries.
This is the verse the question asks about; it directly describes the vile person's character and method of gaining power.
Daniel 9:27: And he shall confirm the covenant with many for one week: and in the midst of the week he shall cause the sacrifice and the oblation to cease, and for the overspreading of abominations he shall make it desolate, even until the consummation, and that determined shall be poured upon the desolate.
Les uses this verse to connect the Antichrist with a seven-year covenant and the later desolation of the temple.
Les says Antiochus the Great and Antiochus Epiphanes are types or pictures of the Antichrist, but the vile person of Daniel 11:21 is the coming end-time ruler, the Antichrist.
According to Les, he will come in with flatteries and political manipulation, not military force. He will have a charismatic personality and promise peace, prosperity, and security for Israel, so the world will welcome him with open arms.
Les says the triggering event is his signing a seven-year treaty with Israel, as in Daniel 9:27, and this cannot happen until believers are gone.
Yes, Les says he will be born of woman, flesh and blood, and used of Satan, much like Judas.
