אֶת־יְהוָ֧ה אֱלֹהֶ֛יךָ תִּירָ֖א אֹת֣וֹ תַעֲבֹ֑ד וּב֣וֹ תִדְבָּ֔ק וּבִשְׁמ֖וֹ תִּשָּׁבֵֽעַ׃
Thou shalt fear the LORD thy God; Him shalt thou serve; and to Him shalt thou cleave, and by His name shalt thou swear.
Targum Jonathan on Deuteronomy
Revere the Lord your God, and worship before Him, and cleave closely to His fear, and swear by His Name.
