Historical evidence identifies the man referred to as "he" as Antiochus Epiphanes. Because the record of his activities against the Jews parallels many of the activities prophesied about the end-time Beast of Revelation, many believe he is a symbolic forerunner of that one to come. This verse prophesies three things of the coming Beast:
First, we normally and correctly associate the Beast with great, though evil, power. However, among other things he will also be a flatterer. He will not only be a person of great political wisdom, but he will be personally persuasive and charming. Proverbs 31:30 warns us, "Charm is deceitful"—all too frequently, it is nothing more than a social and public relations skill used for personal gain. It can be nothing more than a dishonest puffery displayed to get another's cooperation to achieve an ulterior motive. Practically, it can easily become manipulation and control by a skilled person using honeyed words. David's experience with a charming betrayer is recorded in Psalm 55:21: "The words of his mouth were smoother than butter, but war was in his heart; his words were softer than oil, yet they were drawn swords." Politically, this activity is defined as treachery.
Second, this verse also tells us he will corrupt or seduce some of those who have made the covenant with God. At first, we might think that these are the unconverted, but that is not so. This refers to the last phrase of verse 30, where the Beast "shows regard for those who forsake the holy covenant." These are people who apostatize. A person cannot forsake an agreement he has never made. Some of the converted will be seduced by manipulative flatteries and corrupted into cooperation. At the end time, that means some of us! Reader's Digest Encyclopedic Dictionary lists some of the definitions of corrupt: "to pervert the fidelity or integrity of as by bribing; to destroy morally; pervert, ruin, change from the original, debase, contaminate."
Putting these two factors together, we ought to imagine God waving a yellow caution flag before us, revealing an area of danger that we should mark well. It is highly unlikely that any of us will move in the same political, social, and military circles as the Beast. Thus, his personal charm or flatteries will not be used to deceive us in an intimate, personal circumstance. Therefore, his political wisdom and flatteries will be exhibited in his public policies. We must never forget that this man will be of the world and as unconverted as a man can be.
Therefore the political strategies he will use will essentially be appeals to the lust of the flesh, the lust of the eyes, and the pride of life (I John 2:15-17). He will appeal to us to abandon our faith and give our cooperation, trust, and loyalty to him by submitting to political programs and public policies that offer us physical well-being, peace, and safety under his umbrella. It will seem advantageous for us, at least on a short-term basis, to support his programs. He will make glowing promises of preferment, reward, and peace. But never forget, when seduction and subversion through flatteries fail, the reign of terror by persecution begins.
Third and finally, the verse prophesies that those who know their God shall be strong, or stand firm, and do exploits. God inserts this to show us how not to be deceived by flatteries. Jesus says in John 17:3, "This is eternal life, that they may know You, the only true God, and Jesus Christ whom You have sent." Knowing God is the key to seeing through and rejecting the seductive flatteries of the Beast because it is the foundation of faith. We know God gives truths that are eternal.
The Beast will deceive through a combination of outright lies, partial truths, and temporary truths. The people who see through his devious words will do so because they know and believe God and His truth. They will therefore be strong in giving glory to Him. These people will prefer to risk their lives rather than betray God's honor. By believing God, they will be prepared for the Beast's onslaught, and this will give them strength because it produces firm resolve and sense of purpose. Though these prophecies are not yet fulfilled, evidence is accumulating that they are just over the horizon, and thus something we may soon face.
