From the Holy Communion Old Testament reading:
Then the word of the Lord came to him, saying, ‘Go now to Zarephath, which belongs to Sidon, and live there; for I have commanded a widow there to feed you.’ So he set out and went to Zarephath. When he came to the gate of the town, a widow was there gathering sticks; he called to her and said, ‘Bring me a little water in a vessel, so that I may drink.’ As she was going to bring it, he called to her and said, ‘Bring me a morsel of bread in your hand.’ But she said, ‘As the Lord your God lives, I have nothing baked, only a handful of meal in a jar, and a little oil in a jug; I am now gathering a couple of sticks, so that I may go home and prepare it for myself and my son, that we may eat it, and die.’
(1 Kings, chapter 17, verses 8-12, NRSV)
The generosity of the woman to Elijah, and the generosity of God to her as she stepped in faith and dread over the edge of starvation, should make us think.
