2 Kings 6:17-19

Young's Literal Translation

¹⁷ And Elisha prayeth, and saith, `Jehovah, open, I pray Thee, his eyes, and he doth see;' and Jehovah openeth the eyes of the young man, and he seeth, and lo, the hill is full of horses and chariots of fire, round about Elisha.

¹⁸ And they come down unto it, and Elisha prayeth unto Jehovah, and saith, `Smite, I pray Thee, this nation with blindness;' and He smiteth them with blindness, according to the word of Elisha.

¹⁹ And Elisha saith unto them, `This [is] not the way, nor [is] this the city; come after me, and I lead you unto the man whom ye seek;' and he leadeth them to Samaria.
