כִּי־בֵ֭ן הָיִ֣יתִי לְאָבִ֑י רַ֥ךְ וְ֝יָחִ֗יד לִפְנֵ֥י אִמִּֽי׃
Denn ich war ein Sohn meines Vaters, Tender und ein einziger vor meiner Mutter.

For I was a son to my father Lest you say that Solomon hated people because he admonished them concerning robbery and immorality, something a person desires, he therefore states: I was a son, etc., a tender one and an only one, etc., that he loved me very much.
