סֵעֲפִ֥ים שָׂנֵ֑אתִי וְֽתוֹרָתְךָ֥ אָהָֽבְתִּי׃
Samech. Odio quelli che hanno una doppia mente; ma la tua legge mi piace.
Rashi on Psalms
I hate those who harbor iniquitous thoughts Those who think thoughts of iniquity, like (Job 20: 2): “Therefore, my thoughts (סעפי) answer me”; (I Kings 18:21), “between two ideas (הסעפים).” When you read סְעִפִים, it concerns the thought, but when you read סֵעֲפִים, the language refers to those who think it.
