וְעָשִׂ֗יתָ עַל־פִּ֤י הַדָּבָר֙ אֲשֶׁ֣ר יַגִּ֣ידֽוּ לְךָ֔ מִן־הַמָּק֣וֹם הַה֔וּא אֲשֶׁ֖ר יִבְחַ֣ר יְהוָ֑ה וְשָׁמַרְתָּ֣ לַעֲשׂ֔וֹת כְּכֹ֖ל אֲשֶׁ֥ר יוֹרֽוּךָ׃
And thou shalt do according to the tenor of the sentence, which they shall declare unto thee from that place which the LORD shall choose; and thou shalt observe to do according to all that they shall teach thee.
Targum Jonathan on Deuteronomy
Then shall you do according to the word of the custom of the law that they will show you at the place the Lord will choose, and observe to do whatsoever they teach you.
