The Hebrew chataah is a feminine variant form denoting sin or a sin offering. It appears in Genesis 20:9 where Abimelech confronts Abraham: 'What have you done to me? What sin (chataah) have you brought upon me and my kingdom?' The word is used interchangeably with chattath (H2403) and underscores that sin is always communal β it lands on households and kingdoms, not only individuals.
Abimelech's cry to Abraham β 'What sin have you brought upon me?' β reveals the corporate dimension of sin in Hebrew thought. The chataah of one person pollutes the community. This is why the Levitical sin offerings addressed not only individual guilt but the defilement of sacred space. When the high priest entered the Holy of Holies on Yom Kippur, he was not only dealing with personal sins but cleansing the tabernacle/temple from the accumulated chataah of Israel (Leviticus 16:16). Sin contaminates what it touches β which is why atonement requires not just forgiveness but purification.
