The besetting problem I have with it to this day, is do people want to know this?
Old English besettan "to put, place; own, keep; occupy, settle; cover, surround with, besiege," from Proto-Germanic *bisatjan (cf. Old Saxon bisettjan, Dutch bezetten, Old High German bisezzan, German besetzen, Gothic bisatjan); see be- + set (v.). The figurative sense also was in Old English. Related: Beset (past tense); besetting.
