וְאֶל־בְּנֵ֥י יִשְׂרָאֵ֖ל תְּדַבֵּ֣ר לֵאמֹ֑ר אִ֥ישׁ אִ֛ישׁ כִּֽי־יְקַלֵּ֥ל אֱלֹהָ֖יו וְנָשָׂ֥א חֶטְאֽוֹ׃
And thou shalt speak unto the children of Israel, saying: Whosoever curseth his God shall bear his sin.
Targum Jonathan on Leviticus
And speak thou with the sons of Israel, saying: A man young or old who shall blaspheme the known Name of his God shall bear his sin.
