"The jar of flour was not used up and the jug of oil did not run dry, in keeping with the word of the LORD spoken by Elijah." (1 Kings 17:16)
Elijah the Tishbite appears suddenly in 1 Kings with no introduction: he is simply there, a force of nature from Gilead, announcing drought to Ahab. The LORD sends him to the Kerith Ravine where ravens feed him morning and evening and he drinks from the brook. When the brook dries up, God sends him to Zarephath in Sidon where a widow will supply his food. He finds her gathering sticks and asks for water and bread. She says: I only have a handful of flour and a little oil; I am making a last meal for my son and me and then we will die. Elijah says: do not be afraid; make me a small cake first, then make something for yourself and your son. The jar of flour was not used up and the jug of oil did not run dry, in keeping with the word of the LORD spoken by Elijah. Later the widow's son dies; Elijah stretches himself on the boy three times and prays; the boy revives. The widow says: I know that you are a man of God and that the word of the LORD from your mouth is the truth.
The Catechism identifies the widow of Zarephath as the type of the Gentile who receives the prophet: Jesus will cite her in Luke 4 to explain his ministry to outsiders (CCC 2583).
Brothers and sisters, make me a small cake first. Elijah's instruction to the woman who is about to prepare her last meal is the most demanding request in Scripture. Give what you have to God before you use it for yourself. The jar that made the prophet's cake first did not run dry. The jar that saves itself always empties.
Lord God, the jar of flour was not used up and the jug of oil did not run dry. Give us the faith of the widow who gave the prophet his cake first. Let us trust that what we give you first will not leave us empty. Through Christ our Lord. Amen.
