More than one witness was required in criminal cases (Deut. 17:6; 19:15). They were the first to execute the sentence on the condemned (Deut. 13:9; 17:7; 1 Kings 21:13; Matt. 27:1; Acts 7:57, 58). False witnesses were liable to punishment (Deut. 19:16-21). It was also an offence to refuse to bear witness (Lev. 5:1).
