Separation

sep-a-ra'-shun: In the Pentateuch the word niddah specially points to a state of ceremonial uncleanness (Lev 12:2; Lev 12:5; Lev 15:20; Num 6:4; Num 12:13; Num 19:21). For a description of the "water of purification," used for cleansing what was ceremonially unclean (Num 19), see HEIFER, RED; UNCLEANNESS. For "separation" in the sense of nezer, see NAZIRITE.
