In Chapter 12 he speaks of a coming time of mourning from the various family groups. Readying them for the Saviors coming, in chapter 13 he opens his prophetic vision of God’s plan of redemption with a startling graphic picture — a fountain opened to the house of David and the people of Jerusalem to cleanse them from sin and iniquity.
Jesus was from the house of David and he was the source of cleansing for the sinful people of God. Zachariah speaks of Jesus’ cleansing blood as a fountain indicating the abundant flow of God’s sovereign love and mercy. That fountain of mercy and love is ultimately revealed in the shedding of Christ’s blood on Calvary to make a total cleansing from sin.
