Midrash su I Re 17:18

... [What about all] the praise of Joseph, who exceeded in the honor of his father? And yet he did not enter into him all the time, such that were it not that they came to tell him, "Your father is sick," he would not have known! Rather this is to inform you of his righteousness. For he did not want to be alone with his father, lest he say to him, "How did your brothers act with you?" And [then] he would curse them.... Hence he did not go to his father all the time.)

"He and she" (indicate that it was) by the merit of Elijah that they had to eat. After (a period of) days, the son of the woman fell sick and died, as it is said, "And it came to pass after these things that the son of the woman fell sick" (1 Kings 17:17). The woman said to him (Elijah): Thou didst come unto me for coition, and thou wilt bring my sin to remembrance against me, and my son is dead. Now take away all that which thou hast brought to me, and give me my son. Elijah, may he be remembered for good, arose and prayed before the Holy One, blessed be He, and said before Him: Sovereign of all the worlds ! Is it not enough (to endure) all the evils which have befallen me, but also this woman; for I know that out of sorrow for her son has she spoken of a matter which has not occurred, which she has brought against me to vex me. Now let all the generations learn that there is a resurrection of the dead, and restore the soul of this lad within him; and He was entreated of him, as it is said, "And the Lord hearkened unto the voice of Elijah" (1 Kings 17:22). Another Scripture text says, "And Elijah || took the child… See, thy son liveth" (1 Kings 17:23).
