אָרוּר֙ לֹקֵ֣חַ שֹׁ֔חַד לְהַכּ֥וֹת נֶ֖פֶשׁ דָּ֣ם נָקִ֑י וְאָמַ֥ר כָּל־הָעָ֖ם אָמֵֽן׃ (ס)
凡收受賄賂去擊殺無辜之人的，必受咒詛！全體百姓都要說：阿們！
Ibn Ezra
According to many people, he who takes a bribe denotes a judge; but in my opinion, it denotes a false witness.
Sforno
לוקח שוחד להכות, as in the case of Doeg the Edomite (Samuel I, chapter 22), whose accusation was intended to win him favours from the king. Compare also chapter 23 about the Ziphites. Tale-bearing is such a type of interest mentioned in our verse.
Tur HaArokh
לוקח שוחד, “killing for pay.” Most people understand the verse metaphorically, i.e. a judge accepting a bribe to render a guilty verdict where it results in judicial murder. Our author understands it as addressed to the witnesses who perjure themselves for payment, causing the innocent party to be condemned to death by their testimony.
