This chapter has a prayer for the atonement of sins, committed knowingly and committed unawares including those ‘against myself’. This specific verse is SYV (8.13).
“Of the sin against devās, thou art atonement;
of the sin against men, thou art atonement;
of the sin against the Fathers, thou art atonement;
of the sin against myself, thou art atonement;
of every kind of sin, thou art atonement.”
“The sin that I have committed knowingly,
and that I have committed unawares,
of all the sins thou art atonement.” SYV (8.13)
