79.39 · Features of Objects · Sweet, Bitter, Tasteless
sweet, fresh, not bitter, good pertaining to being sweet in contrast with being bitter or salty In a number of languages it would be somewhat misleading to speak of ‘sweet water,’ since this would suggest water to which sugar or some other sweet substance had been added. The equivalent in JAS 3:11 may be ‘fresh water’ or ‘good water’ in contrast with ‘bad water’ or ‘not bitter water’ in contrast with ‘bitter water.’
