כִּ֥י שִׁבְעָתַ֖יִם יֻקַּם־קָ֑יִן וְלֶ֖מֶךְ שִׁבְעִ֥ים וְשִׁבְעָֽה׃
Если Каин будет отмщен семикратно, то Лемех — в семьдесят семь крат!
Targum Jonathan on Genesis
For Kain who sinned and was converted by repentance (had protection) unto seven generations extended to him: and to Lemek, the son of his son, who hath not sinned, it is just that it shall be extended unto seventy and seven.
