Deuteronomy 19:15 Meaning and Commentary

Deuteronomy 19:15

One witness shall not rise up against a man for any iniquity,
or for any sin, in any sin that he sinneth
Whether capital sins, or pecuniary debts; or whatsoever sins a man may be guilty of whether sins against the first or second table of the law, whether greater or lesser sins, whether in moral or civil things; the Jews except only in the case of a woman suspected of adultery and of beheading the heifer:

at the mouth of two witnesses, or at the mouth of three witnesses,
shall the matter be established;
either for acquittance or condemnation; and the witnesses may not, as Jarchi says, write their testimony in a letter, and send it to the sanhedrim, nor may an interpreter stand between the witnesses and the judges; (See Gill on Deuteronomy 17:6).

Deuteronomy 19:15 In-Context

13 Your eye shall not take pity on him, and you shall purge the guilt of innocent blood from Israel, {so that good will be directed toward you}.

14 "You shall not move the boundary [marker] of your neighbor that {former generations} set up on your property in the land that Yahweh your God [is] giving to you to take possession of it.

15 {The testimony of a single witness may not be used to convict} [with respect to] any crime and for any wrongdoing in any offense that a person committed; on the {evidence} of two witnesses or on the {evidence} of three witnesses {a charge shall be sustained}.

16 If {a malicious witness} gets up {to accuse} anyone to testify against him falsely,

17 then the two men {to whom the legal dispute pertains} shall stand {before} Yahweh, {before} the priests and the judges who are [in office] in those days.
