2 Kings 2:15-22

15And when the sons of the prophets who were looking on at Jericho saw him, they said, The spirit of Elijah doth rest on Elisha. And they came to meet him, and bowed themselves to the ground before him. 16And they said to him, Behold now, there are with thy servants fifty strong men; let them go, we pray thee, and seek thy master: lest perhaps the Spirit of the LORD hath taken him up, and cast him upon some mountain, or into some valley. And he said, Ye shall not send.12 17And when they urged him till he was ashamed, he said, Send. They sent therefore fifty men; and they sought three days, but found him not. 18And when they came again to him, (for he tarried at Jericho,) he said to them, Did I not say to you, Go not?

19And the men of the city said to Elisha, Behold, I pray thee, the situation of this city is pleasant, as my lord seeth: but the water is bad, and the ground barren.3 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 spring of the waters, and cast the salt in there, and said, Thus saith the LORD, I have healed these waters; there shall not be from there any more death or barren land . 22So the waters were healed to this day, according to the saying of Elisha which he spoke.
