A reservoir, either natural or artificial, for water. Pits were sometimes used as dungeons, Genesis 37:20; Jeremiah 38:6; or being slightly covered, and baited, they served as traps to catch wild beasts, a device which illustrates the plots of designing men and women, Psalm 119:85; Proverbs 22:14; 26:27; Ezekiel 19:4 . The word pit is also used to denote the grave, Psalm 28:1; 30:3,9; and hell, Revelation 20:1 .
