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 worker of the ground. In the course of time Cain brought to the LORD an offering of the fruit of the ground, and Abel also brought of the firstborn 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 face fell. The LORD said to Cain, "Why are you angry, and why has your face fallen? If you do well, will you not be accepted? And if you do not do well, sin is crouching at the door. Its desire is for you, but you must rule over it.“

Malachi 3:10 (NIV)

Jesus sat down opposite the place where the offerings were put and watched the crowd putting their money into the temple treasury. Many rich people threw in large amounts. But a poor widow came and put in two very small copper coins, worth only a fraction of a penny.

Calling his disciples to him, Jesus said, "I tell you the truth, this poor widow has put more into the treasury than all the others. They all gave out of their wealth; but she, out of her poverty, put in everything—all she had to live on."

Mark 12:41-44 (NIV)

While he was in Bethany, reclining at the table in the home of a man known as Simon the Leper, a woman came with an alabaster jar of very expensive perfume, made of pure nard. She broke the jar and poured the perfume on his head. Some of those present were saying indignantly to one another, "Why this waste of perfume? It could have been sold for more than a year's wages and the money given to the poor." And they rebuked her harshly.

"Leave her alone," said Jesus. "Why are you bothering her? She has done a beautiful thing to me. The poor you will always have with you, and you can help them any time you want. But you will not always have me. She did what she could. She poured perfume on my body beforehand to prepare for my burial. I tell you the truth, wherever the gospel is preached throughout the world, what she has done will also be told, in memory of her."
