Marah: Bitterness, a fountain at the sixth station of the Israelites
(Exodus 15:23,24; Numbers 33:8) whose waters were so bitter that they could
not drink them. On this account they murmured against Moses, who,
under divine direction, cast into the fountain "a certain tree" which
took away its bitterness, so that the people drank of it. This was
probably the 'Ain Hawarah, where there are still several springs of
water that are very "bitter," distant some 47 miles from 'Ayun Mousa.
