2 Kings 2

19 And the men of the city say to Elisha, "Now behold, the site of the city [is] good, as my lord sees, and the waters [are] bad, and the earth sterile." 20 And he says, "Bring a new dish to me, and place salt there"; and they bring [it] to him, 21 and he goes out to the source of the waters, and casts salt there, and says, "Thus said YHWH: I have given healing to these waters; there is not anymore death and sterility there." 22 And the waters are healed to this day, according to the word of Elisha that he spoke.
