What does the Bible say about the miracle of healing bitter water?

In 2 Kings 2:19-22, Elijah is approached by the men of Jericho who express their concern about the city's bitter waters, which led to barrenness and death. Elijah instructs them to bring him a new cruise with salt, and upon casting the salt into the waters, he declares that God has healed them. This act serves as a profound symbol of God's mercy towards sinners, illustrating that just as the waters were made pure again, so too can sinners find healing and life through Christ, who is described as the water of life (John 4:14). The healing of the waters at Jericho is emblematic of the regenerative work God does in the hearts of believers.
