Eclesiastes 9

Eclesiastes 9:8

No one, therefore, can hear the Word of God unless he has first been sanctified, that is, unless he is "holy in body and spirit," unless he has washed his garments. For a little later he shall go in to the wedding dinner, he shall eat from the flesh of the lamb, he shall drink the cup of salvation. Let no one go in to this dinner with dirty garments. Wisdom also has commanded this elsewhere, saying, "Let your garments be clean at all times." For your garments were washed once when you came to the grace of baptism; you were purified in body; you were cleansed from all filth of flesh and spirit. — HOMILIES ON EXODUS 11:7
