‏ Isaiah 43:2

2. rivers ... not overflow thee--so in passing Jordan, though at its "overflow," when its "swellings" were especially dangerous (Jos 3:15; Jr 12:5).

waters ... fire--a proverbial phrase for the extremest perils (Psa 66:12; also Psa 138:7). Literally fulfilled at the Red Sea (Ex 14:21, 22), and in the case of the three youths cast into the fiery furnace for conscience' sake (Da 3:25, 27).
