Leviticus 20:17 to speak of illegitimate sexual relations between siblings. However, there the seeing is mutual. Nor can this be connected to the common Hebrew phrase for incest—to uncover someone’s nakedness (see Lev. 18:6–19)—since Noah uncovered his own nakedness. Another suggestion is that Ham took voyeuristic pleasure in seeing his father naked. However, there is no suggestion of this in the text itself. Instead, Ham’s sin was in not honouring his father by demonstrating discretion and loyalty.
