Rashi on Leviticus 5:22/רש"י על ויקרא ה׳:כ״ב

1וכחש בה AND DENIETH IT — i.e. that he denies על אחת מכל REGARDING ONE OF ALL these things (those mentioned above), אשר יעשה האדם לחטא THAT A MAN DOETH (is apt to do, cf. Numbers 5:7, said of a similar case ‎מכל חטאת האדם) TO SIN and to swear falsely with the object of repudiating a money claim.
