Traitors - This word is used in the New Testament only here and in Luke 6:16; Acts 7:52. It means any one who betrays - whether it be a friend or his country. Treason has been in all ages regarded as one of the worst crimes that man can commit.
Heady - The same word in Acts 19:36, is rendered rashly. It occurs only there and in this place in the New Testament. It properly means "falling forwards; prone, inclined, ready to do anything; then precipitate, headlong, rash." It is opposed to that which is deliberate and calm, and here means that men would be ready to do anything without deliberation, or concern for the consequences. They would engage in enterprises which would only disturb society, or prove their own ruin.
High-minded - Literally, "puffed up;" compare the notes at 1-Timothy 3:6, where the same word is rendered "lifted up with pride." The meaning is, that they would be inflated with pride or self-conceit.
Lovers of pleasures more than lovers of God - That is, of sensual pleasures, or vain amusements. This has been, and is, the characteristic of a great part of the world, and has often distinguished even many who profess religion. Of a large portion of mankind it may be said that this is their characteristic, that they live for pleasure; they have no serious pursuits; they brook no restraints which interfere with their amusements, and they greatly prefer the pleasures to be found in the gay assembly, in the ball-room, or in the place of low dissipation, to the friendship of their Creator.

Traitors - Προδοται· From προ, before, and διδωμι, to deliver up. Those who deliver up to an enemy the person who has put his life in their hands; such as the Scots of 1648, who delivered up into the hands of his enemies their unfortunate countryman and king, Charles the First; a stain which no lapse of ages can wipe out.
Heady - Προπετεις· From προ, forwards, and πιπτω, to fall; headstrong, precipitate, rash, inconsiderate.
High-minded - Τετυφωμενοι· From τυφος, smoke; the frivolously aspiring; those who are full of themselves, and empty of all good.
Lovers of pleasures more than lovers of God - This is nervously and beautifully expressed in the Greek, φιληδονοι μαλλον η φιλοθεοι lovers of pleasure rather than lovers of God; i.e. pleasure, sensual gratification, is their god; and this they love and serve; God they do not.

Traitors,.... To their princes and sovereigns, whose deaths they have contrived and compassed, and whom they have assassinated and murdered; and have been betrayers of the secrets of persons, which they have come at by auricular confession to them; and of their best and nearest friends, to preserve and secure themselves.
Heady; rash, daring, bold, and impudent, fit to say and do any thing, though ever so vile and wicked.
High, minded; puffed and swelled up with a vain conceit of themselves, and speaking great swelling words of vanity;
lovers of pleasure more than lovers of God; lovers of sinful pleasures, or the pleasures of sin, which are but for a season, and not God; serving divers lusts and pleasures, and not God; making a god of their belly; sensual idolaters, delighting themselves in their carnal lusts, and not in the service of God.

heady--precipitate in action and in passion.
high-minded--literally, "puffed up" with pride, as with smoke blinding them.
lovers of pleasure . . . God--Love of pleasure destroys the love and sense of God.

Lovers of sensual pleasure - Which naturally extinguishes all love and sense of God.
