John Gill Commentary 1 Kings 17:20

"And he cried unto Jehovah, and said, O Jehovah my God, hast thou also brought evil upon the widow with whom I sojourn, by slaying her son?" — 1 Kings 17:20 (ASV)

And he cried unto the Lord
Or prayed unto him, as the Targum, with great vehemence and importunity:

and said, O Lord, my God, have you also brought evil upon the widow,
with whom I sojourn, by slaying her son ?
he pleads his interest in the Lord, and makes use of it as an argument with him to hear his prayer; he observes the character and condition of the woman, a widow, such as the Lord has a compassionate regard for; and he urges the kindness of her to him, with whom he had sojourned so long; and seems to represent the case as an additional evil or affliction to him, as well as to the widow.
