עַל־פִּ֣י ׀ שְׁנַ֣יִם עֵדִ֗ים א֛וֹ שְׁלֹשָׁ֥ה עֵדִ֖ים יוּמַ֣ת הַמֵּ֑ת לֹ֣א יוּמַ֔ת עַל־פִּ֖י עֵ֥ד אֶחָֽד׃
At the mouth of two witnesses, or three witnesses, shall he that is to die be put to death; at the mouth of one witness he shall not be put to death.
Targum Jonathan on Deuteronomy
Upon the word of two witnesses or of three he shall die who is guilty of death; they shall not be put to death on the word of one witness.
