Cyrill of Alexandria
Cyril mentions various forms of impurities, each requiring a means of purification, fulfilled in Christ. He states: "If anyone sins after hearing the voice of an oath, whether as a witness, having seen it, or knowing of it without reporting it, he will bear guilt. Should he accidentally touch something unclean, such as the carcass of an unclean animal, he remains unclean and guilty, even if he was unaware. Likewise, if he touches a human's uncleanness, whatever that may be, and later becomes aware, he is held accountable. Furthermore, if someone carelessly swears an oath to commit an act, whether good or bad, without realizing it at first but later comes to know, he is guilty.

If anyone is guilty of any of these, he must confess his sin and offer a sacrifice, such as a sheep or goat, to the Lord for atonement, and through the priest, he shall be cleansed from his sin" (Leviticus 5:1-6). It is crucial to note that a person who hears the voice of an oath, remaining entirely innocent, may still become implicated in other forms of impurity, thereby being found guilty of a false oath. The gravest defilement stems from disdain for God, paralleling the transgressions linked to physical impurities. Should a cursed false oath not be regarded with equal seriousness as contempt for oaths? Palladius agrees, noting that the faults in both instances are indeed of equal weight.
