Genesis 4:13-14

(13, 14) My punishment (or my iniquity) is greater than I can bear.—Literally, than can be borne, or “forgiven.” It is in accordance with the manner of the Hebrew language to have only one word for an act and its result. Thus work and wages are expressed by the same word in Isaiah 62:11. The full meaning, therefore, is, “My sin is past forgiveness, and its result is an intolerable punishment.” This latter idea seems foremost in Cain’s mind, and is dwelt upon in Genesis 4:14. He there complains that he is driven, not “from the face of the earth,” which was impossible, but from the adâmâh, his dear native soil, banished from which, he must go into the silence and solitude of an earth unknown and untracked. And next, “from thy face shall I be hid.” Naturally, Cain had no idea of an omnipresent God, and away from the adâmâh he supposed that it would be impossible to enjoy the Divine favour and protection. Without this there would be no safety for him anywhere, so that he must rove about perpetually, and “every one that findeth me shall slay me.” In the adâmâh Jehovah would protect him; away from it, men, unseen by Jehovah, might do as they liked. But who were these men? Some commentators answer, Adam’s other sons, especially those who had attached themselves to Abel. Others say that Adam’s creation was not identical with that of Genesis 1:27, but was that of the highest type of the human race, and had been preceded by the production of inferior races, of whose existence there are widespread proofs. But others, with more probability, think that Cain’s was a vain apprehension. How could he know that Adam and his family were the sole inhabitants of the earth? Naturally he expected to find farther on what he had left behind; a man and woman with stalwart sons: and that these, regarding him as an interloper come to rob them, and seeing in his ways proof of guilt, would at once attack and slay him.
