Although they are 2 books in our Bible, 1 & 2 Kings were originally written as one book telling a unified story about the history of the kings and of Israel/Judah, and the prophets, and God raised up to confront them. Elijah is one of those prophets and God works 7 great miracles through him, demonstrating Elijah’s authority to speak for God. Elisha is Elijah’s disciple and asks for a double portion of his sprit (2 Ki 2:9). 14 miracles are recorded of Elishas and the widows oil miracle is one of those.
