Genesis 4:14

Behold, 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. In bitter resentment the words pour forth from the mouth of Cain, accusing God of denying him as much as a single spot on the face of the earth where his foot might find rest. Moreover, whereas God had formerly revealed Himself also to him in the worship of the family, Cain now was condemned to be hidden from the face of God, in constant danger of the avenger of blood who might arise from among his brothers and sisters. The complaint of Cain was at the same time a plea for some sort of assurance on the part of God respecting his own safety.
