'Flour' in the Bible

The food of Solomon for one day was thirty dry measures of choice meal and sixty dry measures of flour;

She said, "{As Yahweh your God lives}, surely I do not have a cake, {but only a handful of flour} in the jar and a little olive oil in the jug. Here I [am] gathering a few pieces of wood, and I will go and prepare it for me and my son, that we might eat it and die."

For thus says Yahweh, the God of Israel: 'The jar of flour will not be emptied and the jug of olive oil will not run out until the day Yahweh gives rain on the surface of the earth.'"

The jar of flour was not emptied and the jug of olive oil did not run out, according to the word of Yahweh which he spoke by the hand of Elijah.
