Cain in Fausset's Bible Dictionary

(acquired). For Eve said, "I have gotten a man from (or with the help of) Jehovah." She recognized this gift of Jehovah, though accompanied with the foretold "sorrow" of conception, as a first step toward fulfilling the promise of the Redeemer, "the seed of the woman" (Genesis 3:15). Cain, her supposed acquisition, proved a deadly loss. Parents' expectations are very different from after realities. Cain was of that wicked one (1 John 3:12), not associated with Jehovah, except as incurring His curse. Augustine (City of God, 15:1) says: "Cain, the author of the city of the world, is born first, and is called an acquisition because he buildeth a city, is given to the cares and pomp of the world, and persecutes his brother that was chosen out of the world. But (See ABEL (see), the beginner of the city of God, is born second, called 'vanity' because he saw the world's vanity, and is therefore driven out of the world by an untimely death. So early came martyrdom into the world; the first man that died died for religion."...
