The LORD is merciful to Cain

13And Cain said unto the LORD, My punishment is greater than I can bear. 14Behold, thou hast driven me out this day from the face of the earth; and from Thy face shall I be hid; and I shall be a fugitive and a vagabond in the earth; and it shall come to pass, that every one that findeth me shall slay me. 15And the LORD said unto him, Therefore whosoever slayeth Cain, vengeance shall be taken on him sevenfold. And the LORD set a mark upon Cain, lest any finding him should kill him. 16And Cain went out from the presence of the LORD, and dwelt in the land of Nod, on the east of Eden. Gensis 4:12 - 16
