2 Kings 2:15-22

15And the sons of the prophets who were at Jericho on the opposite side saw him, and they said, The spirit of Elijah rests on Elisha. And they came to meet him, and bowed themselves to the ground before him,

16and said to him, Behold now, there are with thy servants fifty valiant men; let them go, we pray thee, and seek thy master, lest perhaps the Spirit of Jehovah have taken him up, and cast him upon some mountain, or into some ravine. And he said, Ye shall not send.

17And they pressed him till he was ashamed, and he said, Send. They sent therefore fifty men, and they sought three days, but did not find him.

18And they came again to him (now he was staying at Jericho); and he said to them, Did I not say to you, Go not?

19And the men of the city said to Elisha, Behold now, the situation of the city is good, as my lord sees; but the water is bad, and the land is barren.

20And he said, Bring me a new cruse, and put salt in it. And they brought it to him.

21And he went forth to the source of the waters, and cast the salt in there, and said, Thus saith Jehovah: I have healed these waters: there shall not be from thence any more death or barrenness.

22And the waters were healed to this day, according to the saying of Elisha which he spoke.
