לִבִּ֣י סְ֭חַרְחַר עֲזָבַ֣נִי כֹחִ֑י וְֽאוֹר־עֵינַ֥י גַּם־הֵ֝֗ם אֵ֣ין אִתִּֽי׃
Serce moje kołace, opuściła mnie siła moja, a światło oczu moich, i ono nie ostało się przy mnie.
Ibn Ezra
פקחקח The opening of the prison. It is one word, with the reduplication of the second and third radical; it is similar in form to סחרחר panteth (Ps. 38:11), אדמדם red (Lev. 13:49), ירקרק green (Lev. ibid).
Rabbeinu Bahya
והאספסף, “and the rabble,” these people were the fellow travelers, they were not natural born Israelites. They were described elsewhere as ערב רב, “a mixed multitude.” The word אספסף, is a doubling of certain letters just as we find in the word סחרחר, or חמרמרו מעי in Psalms 38,11 (reeling) or in Lamentations 1,20 (my entrails are distressed).
Rashi
ופתלתל entortille in old French, Engl, twisted: like a thread (פתיל), which one twines and twists round the central strand. The word פתלתל is of the “doubled” words (in which the two last letters are the same), like (Leviticus 13:49): ירקרק. אדמדם; (Psalms 38:31): סחרחר; (1 Kings 7:23; Targum Jonathan on): סגלגל.
