BLOODGUILTINESS

blud-gilt'-i-nes: Found in the King James Version only in Psalms 51:14. The Revised Version (British and American) adds Exodus 22:2-3; 1 Samuel 25:26,33. Ezekiel 18:13 seems to indicate that the phrase does not necessarily signify bloodshed, but any grievous sin which, if it remains, will block God's favor to His land and people (compare Deuteronomy 21:8; Isaiah 1:15). Psalms 51 is to be interpreted in this light.
