Hebrew

ˀby - to want, be willing (HALOT 3)

As observed by T. Nöldeke (1904:66), the Hebrew verb is almost always coupled with negative particles: lō(ˀ) ˀābā ‘he did not want,’ etc. (for a strikingly similar structural parallel in Old Assyrian lā muˀāˀum ‘not to want’ see Veenhof 1986)(Kogan 2015: 277)
