What Is Cruse in the Bible?

What the Bible says

1 Kings 17:12-16

¹²And she answered: As the Lord thy God liveth, I have no bread, but only a handful of meal in a pot, and a little oil in a cruse: behold I am gathering two sticks that I may go in and dress it, for me and my son, that we may eat it, and die. ¹³And Elias said to her: Fear not, but go, and do as thou hast said: but first make for me of the same meal a little hearth cake, and bring it to me: and after make for thyself and thy son. ¹⁴For thus saith the Lord the God of Israel: The pot of meal shall not waste, nor the cruse of oil be diminished, until the day wherein the Lord will give rain upon the face of the earth. ¹⁵She went and did according to the word of Elias: and he ate, and she, and her house: and from that day ¹⁶The pot of meal wasted not, and the cruse of oil was not diminished, according to the word of the Lord, which he spoke in the hand of Elias.
