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.

Elijah went--a marvellous proof of the natural intrepidity of this prophet, of his moral courage, and his unfaltering confidence in the protecting care of God, that he ventured to approach the presence of the raging lion.
there was a sore famine in Samaria--Elijah found that the famine was pressing with intense severity in the capital. Corn must have been obtained for the people from Egypt or the adjoining countries, else life could not have been sustained for three years; but Ahab, with the chamberlain of his royal household, is represented as giving a personal search for pasture to his cattle. On the banks of the rivulets, grass, tender shoots of grass, might naturally be expected; but the water being dried up, the verdure would disappear. In the pastoral districts of the East it would be reckoned a most suitable occupation still for a king or chief to go at the head of such an expedition. Ranging over a large tract of country, Ahab had gone through one district, Obadiah through another.

Elijah went - Wherein he shews a strong faith, and resolute obedience, and invincible courage, that he durst at God's command run into the mouth of this raging lion.
