³ sn The oath to testify was not an oath to tell the truth before a court of law in the modern sense. Instead it was a “curse” or “imprecation” expressed by the victim of the theft, or by the legal authorities, called down on any witness of the crime who kept silent or refused to testify (as here). According to Lev 5:1, if a witness does not speak up he is accountable for the crime. This person hears the adjuration, but if he speaks up he is condemned, and if he does not speak up he is guilty under the law. The proverb is an unusual one; it seems to be warning against getting mixed up in any way with the thief, for it will create a serious ethical dilemma.
