John Gill Commentary 1 Kings 18:2

"And Elijah went to show himself unto Ahab. And the famine was sore in Samaria." — 1 Kings 18:2 (ASV)

And Elijah went to show himself unto Ahab
Which showed his cheerful and ready obedience to the will of God, and his great courage and magnanimity, to face a king enraged against him, and that sought his life:

and there was a sore famine in Samaria ;
the metropolis of the kingdom, where Ahab kept his court, and therefore must be sensible of it, and bore the greater indignation against the prophet who had foretold it.
