שְׁמֹ֣ר רגליך [רַגְלְךָ֗] כַּאֲשֶׁ֤ר תֵּלֵךְ֙ אֶל־בֵּ֣ית הָאֱלֹהִ֔ים וְקָר֣וֹב לִשְׁמֹ֔עַ מִתֵּ֥ת הַכְּסִילִ֖ים זָ֑בַח כִּֽי־אֵינָ֥ם יוֹדְעִ֖ים לַעֲשׂ֥וֹת רָֽע׃
Guard thy foot when thou goest to the house of God, and be ready to hearken: it is better than when fools give sacrifices; for they know not that they do evil.
