1 Kings 17:10-14 (NIV)
So he went to Zarephath. When he came to the town gate, a widow was there gathering sticks. He called to her and asked, “Would you bring me a little water in a jar so I may have a drink?” 11 As she was going to get it, he called, “And bring me, please, a piece of bread.” 12 “As surely as the Lord your God lives,” she replied, “I don’t have any bread—only a handful of flour in a jar and a little olive oil in a jug. I am gathering a few sticks to take home and make a meal for myself and my son, that we may eat it—and die.” 13 Elijah said to her, “Don’t be afraid. Go home and do as you have said. But first make a small loaf of bread for me from what you have and bring it to me, and then make something for yourself and your son. 14 For this is what the Lord, the God of Israel, says: ‘The jar of flour will not be used up and the jug of oil will not run dry until the day the Lord sends rain on the land.’” 

Matthew 13:31-32 (NIV)
He told them another parable: “The kingdom of heaven is like a mustard seed, which a man took and planted in his field. 32 Though it is the smallest of all seeds, yet when it grows, it is the largest of garden plants and becomes a tree, so that the birds come and perch in its branches.” 

2 Samuel 24:21-25 (NIV)
David replied, “I have come to buy your threshing floor and to build an altar to the Lord there, so that he will stop the plague.” 22 “Take it, my lord the king, and use it as you wish,” Araunah said to David. “Here are oxen for the burnt offering, and you can use the threshing boards and ox yokes for wood to build a fire on the altar.23 I will give it all to you, Your Majesty, and may the Lord your God accept your sacrifice.” 24 But the king replied to Araunah, “No, I insist on buying it, for I will not present burnt offerings to the Lord my God that have cost me nothing.” So David paid him fifty pieces of silver for the threshing floor and the oxen. 25 David built an altar there to the Lord and sacrificed burnt offerings and peace offerings. And the Lord answered his prayer for the land, and the plague on Israel was stopped.
