לָקֹ֗חַ אֵ֣ת סֵ֤פֶר הַתּוֹרָה֙ הַזֶּ֔ה וְשַׂמְתֶּ֣ם אֹת֔וֹ מִצַּ֛ד אֲר֥וֹן בְּרִית־יְהוָ֖ה אֱלֹהֵיכֶ֑ם וְהָֽיָה־שָׁ֥ם בְּךָ֖ לְעֵֽד׃
’Take this book of the law, and put it by the side of the ark of the covenant of the LORD your God, that it may be there for a witness against thee.
Targum Jonathan on Deuteronomy
Take the book of this law, and put it into a chest on the right side of the ark of the covenant of the Lord your God, that it may be for a testament to you.
