וּשְׁמַרְתֶּ֣ם לַעֲשׂ֔וֹת כַּאֲשֶׁ֥ר צִוָּ֛ה יְהוָ֥ה אֱלֹהֵיכֶ֖ם אֶתְכֶ֑ם לֹ֥א תָסֻ֖רוּ יָמִ֥ין וּשְׂמֹֽאל׃
Ye shall observe to do therefore as the LORD your God hath commanded you; ye shall not turn aside to the right hand or to the left.
Targum Jonathan on Deuteronomy
And now observe to do as the Lord your God hath commanded you; decline not to the right hand or to the left.
