I have another reason for posting it. For the first time last night, I noticed someone had posted the Old Testament reference Zechariah 13:1 (KJV) under the video:
In that day there shall be a fountain opened to the house of David
and to the inhabitants of Jerusalem, for sin and for uncleanness.
This made me cry.
You -- You! -- are the fountain, Jesus.
Your precious body became a healing fountain for me.
Here is the hymn, written by William Cowper probably in 1771 or 1772, and performed here by A Capella Christian Music.
(There may be a short ad right before the YouTube video -- sorry.)
