Swearing. We are accountable for the sins of others, to which we are accessory, as appears from this and part of the following chapter. No distinction of persons is here noticed. If any one, therefore, be witness to another’s promise, confirmed by oath, and, being cited to the bar, refuse to speak, he shall be guilty of sin, and offer the sacrifice proscribed (ver. 6,) for all the preceding cases. Restitution must also be made to the injured person. (Menochius)

But others suppose that no sacrifice was allowed for such an obstinate wretch as when not answered when the judge swore or adjured him. He was liable to be put to death. The associate of the thief fell under the like punishment as the thief himself, when he would not reveal the theft to the judge, Proverbs xxix. 24. Others again understand this swearing to mean blaspheming God. If the hearer do not reprehend him, he shall suffer as his accomplice. (Origen; Philo)

Junius thinks that the neglect of fraternal correction, was to be expiated by the sacrifice prescribed for the sins of ignorance, concerning which Moses is treating. But it seems that the person here mentioned was to die, as the words he shall bear his iniquity, commonly denote, chap. xix. 8.; &c. (Calmet)

When perjury prejudiceth another’s cause, we are bound to reveal what we know to the judge, if it can be done so as to avoid scandal. (Worthington)

Not. Hebrew editions read loa, instead of la, both here and in 34 other places; an irregularity unknown in some manuscripts, and to the Samaritan copy. Perhaps it may have been occasioned by lu, “to him,” being of the same sound with la. (Kennicott)
