Deuteronomy 5:20
18 “You must not commit adultery. 19 “You must not steal. 20 “You must not offer false testimony against another. 21 You must not desire another man’s wife, nor should you crave his house, his field, his male and female servants, his ox, his donkey, or anything else he owns.” 22 The Lord said these things to your entire assembly at the mountain from the middle of the fire, the cloud, and the darkness with a loud voice, and that was all he said. Then he inscribed the words on two stone tablets and gave them to me.
1 Kings 21:10
8 She wrote out orders, signed Ahab’s name to them, and sealed them with his seal. She then sent the orders to the leaders and to the nobles who lived in Naboth’s city. 9 This is what she wrote: “Observe a time of fasting and seat Naboth in front of the people. 10 Also seat two villains opposite him and have them testify, ‘You cursed God and the king.’ Then take him out and stone him to death.” 11 The men of the city, the leaders, and the nobles who lived there followed the written orders Jezebel had sent them. 12 They observed a time of fasting and put Naboth in front of the people.
Notes and References
"... There are eight other places in the Hebrew Bible where occurs “a witness against” or “to testify against.” In every instance, the texts make it clear that the person against whom the witness testifies is the defendant in the trial. (The term in Job 10:17 is also used in connection to mean “against” ... In addition, 1 Kings 21:10 and 13 employ it) There is a second expression that carries the meaning “to testify against” when it occurs in connection with texts that refer to witnesses with the term. This expression includes the verb “to answer, respond”) and the preposition; again, the defendant occurs as the object of the preposition. For example, the statement from the Decalogue concerning false witness utilizes this expression. Both Exodus 20:16 and Deuteronomy 5:20 include the phrase (“you shall not testify against your neighbor...”) ... Deuteronomy 19:16, states: “If a malicious witness rises against a person to testify against him falsely ...” The expression “to testify against him” explicates what it means for a witness to rise up or appear “against a person” ..."
