Numbers 5:6

To commit, against one another, ver. 7. (St. Augustine, q. 9.) When the thing is secret, so that the judges cannot take cognizance of it, the offender must nevertheless abide by the decision of the priest. Moses condemns him who had stolen an ox to restore it with another, or even to give five oxen, if he have not the one stolen in his possession, Exodus xxii. 1, 4. (Haydock) --- Here to reward the sincerity of the man, who confesses his private fault, he only requires the thing itself to be restored, with a fifth part besides. (Calmet) --- Negligence, not with contempt; (Menochius) though he knows that he is transgressing the divine and natural law. (Tirinus)
