Hastings' Dictionary of the Bible
ONYCHA ( shÄ•chÃ§leth , Exodus 30:34 ). One of the ingredients of the sacred composition which gave a sweet smell when burned (cf. Sir 24:15 , where apparently the same substance is referred to as onyx ). Onycha was obtained from the claw-like [hence the name from Gr. onyx ‘nail’] operculum of some mollusc of the genus strombus . A similar product is still used in Upper Egypt for fumigations.
