סְמוּכִ֣ים לָעַ֣ד לְעוֹלָ֑ם עֲ֝שׂוּיִ֗ם בֶּאֱמֶ֥ת וְיָשָֽׁר׃
אױפֿגעהאַלטן אױף אײביק און שטענדיק, געמאַכט מיט אמת און יושר.
Rashi
Steadfast are His commandments, supported by might, strengthened with punishments and warnings, and the chapters are set one next to the other in sequence and to expound on them. This is what Solomon said (Song 5:15): “His thighs are pillars of marble, etc.”
