The word(s) "trunks" appears 4 time(s) in 4 verse(s) in Quran in Saheeh International translation.

(1) [Pharaoh] said, "You believed him before I gave you permission. Indeed, he is your leader who has taught you magic. So I will surely cut off your hands and your feet on opposite sides, and I will crucify you on the trunks of palm trees, and you will surely know which of us is more severe in [giving] punishment and more enduring."

(2) Extracting the people as if they were trunks of palm trees uprooted.

(3) Whatever you have cut down of [their] palm trees or left standing on their trunks - it was by permission of Allah and so He would disgrace the defiantly disobedient.

(4) Which Allah imposed upon them for seven nights and eight days in succession, so you would see the people therein fallen as if they were hollow trunks of palm trees.
