Adam Clarke on Galatians 5:20

Idolatry - Worshipping of idols; frequenting idol festivals; all the rites of Bacchus, Venus, Priapus, etc., which were common among the Gentiles.

Witchcraft - Φαρμακεια, from φαρμακον a drug or poison; because in all spells and enchantments, whether true or false, drugs were employed. As a drug, φαρμακον, might either be the means of removing an evil, or inflicting one, etymologists have derived it from φερον ακος, bringing ease, or φερον αχος, bringing pain. So spells and incantations were used sometimes for the restoration of the health; at others, for the destruction of an enemy. Sometimes, these φαρμακα were used to procure love; at other times, to produce hatred.

Hatred - Εχθραι· Aversions and antipathies, when opposed to brotherly love and kindness.

Variance - Ερεις· Contentions, where the principle of hatred proceeds to open acts; hence contests, altercations, lawsuits, and disputes in general.

Emulations - Ζηλοι· Envies or emulations; that is strife to excel at the expense of another; lowering others to set up one's self; unholy zeal, fervently adopting a bad cause, or supporting a good one by cruel means. Inquisitions, pretending to support true religion by torturing and burning alive those who both profess and practice it.

Wrath - Θυμοι· Turbulent passions, disturbing the harmony of the mind, and producing domestic and civil broils and disquietudes.

Strife - Επιθειαι· Disputations, janglings, logomachics, or strife about words.

Seditions - Διχοστασιαι· Divisions into separate factions; parties, whether in the Church or state.

Heresies - Αἱρεσεις· Factions; parties in the Church separating from communion with each other, and setting up altar against altar. The word, which is harmless in itself, is here used in a bad sense. In stead of αἱρεσεις the Slavonic has σκανδαλα, scandals, offenses or stumbling-blocks.
