Οὐ παραδέξῃ ἀκοὴν ματαίαν. οὐ συγκαταθήσῃ μετὰ τοῦ ἀδίκου γενέσθαι μάρτυς ἄδικος.
You shall not accept a baseless hearsay. You shall not agree with the unjust to become an unjust witness.
לא תשׂא שׁמע שׁוא אל־תשׁת ידך עם־רשׁע להית עד חמס׃
* accept, i.e. admit as true
* baseless hearsay OR baseless report OR vain report
