Curse and Mark of Cain - Mark of Cain

The Hebrew word for mark ('Oth, אות) could mean a sign, omen, warning, or remembrance. The mark of Cain is God's promise to Cain for divine protection from premature death with the stated purpose to prevent anyone from killing him. It is not known what the mark is, but it is assumed that the mark is visible. Some have speculated that the mark is a Hebrew letter placed on either the face or the arm. The Septuagint translates the mark as a "sign". Thus, it is speculated that the mark served as a sign to others to not commit the same offense.
