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)
Arabic
ˀby - to refuse (Lane 12)
note the wide presence of ˀabā ‘to want’ in a variety of Arabic dialects, notably those of Southern Arabia (GD 11‒62, Behnstedt 5‒6, DRS 3)
Minaean
ˀby - to refuse (LM 1)
Geez
ˀabaya - to refuse (CDG 6)
