'Mirage' in the Bible

And the mirage hath become a pond, And the thirsty land fountains of waters, In the habitation of dragons, Its place of couching down, a court for reed and rush.

They do not hunger, nor thirst, Nor smite them doth mirage and sun, For He who is pitying them doth lead them, And by fountains of waters doth tend them.

Why has my pain become unending,my wound incurable,refusing to be healed?You truly have become like a mirage to me—water that is not reliable.
