<p>for-fold:</p><p>Occurs but twice in English Versions: 2Sa 12:6, "He shall restore the lamb fourfold"; and Lu 19:8 the King James Version, "If I have wrongfully exacted ought .... I restore fourfold." From this statement of Zaccheus we are to understand that fourfold the amount of that which was stolen was the restoration the law required of a thief.
