Go, wash in the pool of Siloam, ... Sent, etc. - (See 2Ki 5:10, 2Ki 5:14). As the prescribed action was purely symbolical in its design, so in connection with it the Evangelist notices the symbolical name of the pool as in this case bearing testimony to him who was sent to do what it only symbolized. (See Isa 8:6, where this same pool is used figuratively to denote “the streams that make glad the city of God,” and which, humble though they be, betoken a present God of Israel.)
