Then he saith, I will return into my house from whence I came out; and when he is come, he findeth it empty, swept, and garnished. Into my house - The soul of that person from whom he had been expelled by the power of Christ, and out of which he was to have been kept by continual prayer, faith, and watchfulness.
He findeth it empty - Unoccupied, σχολαζοντα, empty of the former inhabitant, and ready to receive a new one: denoting a soul that has lost the life and power of godliness, and the testimony of the Holy Spirit.
Swept and garnished - As σχολαζω signifies to be idle, or unemployed, it may refer here to the person, as well as to his state. His affections and desires are no longer busied with the things of God, but gad about, like an idle person, among the vanities of a perishing world. Swept, from love, meekness, and all the fruits of the Spirit; and garnished, or adorned, κεκοσμημενον, decorated, with the vain showy trifles of folly and fashion. This may comprise also smart speeches, cunning repartees, etc., for which many who have lost the life of God are very remarkable.
