Kings IV 6:18 In-Context

16 And Elisaie said, Fear not, for they who are with us more than they that are with them.
17 And Elisaie prayed, and said, Lord, open, I pray thee, the eyes of the servant, and let him see. And the Lord opened his eyes, and he saw: and, behold, the mountain full of horses, and there were chariots of fire round about Elisaie.
18 And they came down to him; and he prayed to the Lord, and said, Smite, I pray thee, this people with blindness. And he smote them with blindness, according to the word of Elisaie.
19 And Elisaie said to them, This not the city, and this not the way: follow me, and I will bring you to the man whom ye seek. And he led them away to Samaria.
20 And it came to pass when they entered into Samaria, that Elisaie said, Open, I pray thee, O Lord, their eyes, and let them see. And the Lord opened their eyes, and they saw; and, behold, they were in the midst of Samaria.
