Genesis 3:21-4:7 (2nd Monday of Lent)
And the LORD God made for Adam and for his wife garments of skins, and clothed them. Then the LORD God said, "Behold, the man has become like one of us, knowing good and evil; and now, lest he put forth his hand and take also of the tree of life, and eat, and live for ever" -- therefore the LORD God sent him forth from the garden of Eden, to till the ground from which he was taken. He drove out the man; and at the east of the garden of Eden he placed the cherubim, and a flaming sword which turned every way, to guard the way to the tree of life.
Now Adam knew Eve his wife, and she conceived and bore Cain, saying, "I have gotten a man with the help of the LORD." And again, she bore his brother Abel. Now Abel was a keeper of sheep, and Cain a tiller of the ground. In the course of time Cain brought to the LORD an offering of the fruit of the ground, and Abel brought of the firstlings of his flock and of their fat portions. And the LORD had regard for Abel and his offering, but for Cain and his offering he had no regard. So Cain was very angry, and his countenance fell. The LORD said to Cain, "Why are you angry, and why has your countenance fallen? If you do well, will you not be accepted? And if you do not do well, sin is couching at the door; its desire is for you, but you must master it.
