וּקְשַׁרְתָּ֥ם לְא֖וֹת עַל־יָדֶ֑ךָ וְהָי֥וּ לְטֹטָפֹ֖ת בֵּ֥ין עֵינֶֽיךָ׃
און זאָלסט זײ אָנבינדן פֿאַר אַ צײכן אױף דײַן האַנט, און זײ זאָלן זײַן פֿאַר אַ שטערנבאַנד צװישן דײַנע אױגן.
Mishnah Sanhedrin
There is greater stringency in respect to the teachings of the scribes than in respect to the torah: [thus,] if [a rebellious elder] says, there is no commandment of tefillin, so that a biblical law may be transgressed, he is exempt. [But if he rules that the tefillin must contain] five compartments, thus adding to the words of the scribes, he is liable.
