Charles Ellicott Commentary 1 Kings 18:41

"And Elijah said unto Ahab, Get thee up, eat and drink; for there is the sound of abundance of rain." — 1 Kings 18:41 (ASV)

Get thee up, eat and drink. —There seems a touch of scorn in these words. Ahab, remaining passive throughout, had descended to the place of slaughter in the valley, looking on silently—if not unmoved—while the priests, whose worship he had openly or tacitly sanctioned, were slain by hundreds. Now Elijah told him to get up to his palace, assuming that, fresh from that horrible sight, he is still ready to feast and rejoice over the approaching removal of the judgment, which alone had affected his shallow nature. The king goes to revel, the prophet to pray.
