159:1.7

[The use of the term seventy-seven as an illustration of mercy and forbearance was derived from the Scriptures referring to Lamech’s exultation because of the metal weapons of his son Tubal-Cain, who, comparing these superior instruments with those of his enemies, exclaimed: “If Cain, with no weapon in his hand, was avenged seven times, I shall now be avenged seventy-seven.”]
