Consider also Greek #4696 spilŏs ‘a spot’, ‘defect’, ‘disgrace’. (#784 aspilŏs ‘without spot’.) The mark of an idolater may be referred to as a “spot”. In the New Testament it may be referred to in: Eph. 5:27; 1 Tim. 6:14; 2 Peter 3:14.

Hebrew #07865 Sîy’ôn = ‘Sion’, ‘peak’, ‘the summit of Mt. Hermon’, from 07863, ‘elevation’, ‘excellency’
