Zechariah 13:1

The penitential supplication of Israel will lead to a thorough renewal of the nation, since the Lord will open to the penitent the fountain of His grace for the cleansing away of sin and the sanctifying of life. Zac 13:1. "In that day will a fountain be opened to the house of David, and to the inhabitants of Jerusalem, for sin and uncleanness." As the Lord Himself pours out the spirit of supplication upon Israel, so does He also provide the means of purification from sin. A fountain is opened, when its stream of water bursts forth from the bosom of the earth (see Isa 41:18; Isa 35:6). The water, which flows from the fountain opened by the Lord, is a water of sprinkling, with which sin and uncleanness are removed. The figure is taken partly from the water used for the purification of the Levites at their consecration, which is called מי חטּאת, sin-water, or alter of absolution, in Num 8:7, and partly from the sprinkling-water prepared from the sacrificial ashes of the red heifer for purification from the defilement of death, which is called מי נדּה, water of uncleanness, i.e., water which removed uncleanness, in Num 19:9. Just as bodily uncleanness is a figure used to denote spiritual uncleanness, the defilement of sin (cf. Psa 51:9), so is earthly sprinkling-water a symbol of the spiritual water by which sin is removed. By this water we have to understand not only grace in general, but the spiritual sprinkling-water, which is prepared through the sacrificial death of Christ, through the blood that He shed for sin, and which is sprinkled upon us for the cleansing away of sin in the gracious water of baptism. The blood of Jesus Christ cleanseth us from all sin (Jo1 1:7; compare Jo1 5:6).

Behold the Lamb of God taking away the sin of the world, the sin of the church; for therefore was the Son of God manifested, to take away our sin, Jo1 3:5. I. He takes away the guilt of sin by the blood of his cross (Zac 13:1): In that day, in the gospel-day, there shall be a fountain opened, that is, provision made for the cleansing of all those from the pollutions of sin who truly repent and are sorry for them. In that day, when the Spirit of grace is poured out to set them a mourning for their sins, they shall not mourn as those who have no hope, but they shall have their sins pardoned, and the comfort of their pardon in their bosoms. Their consciences shall be purified and pacified by the blood of Christ, which cleanses from all sin, Jo1 1:7. For Christ is exalted to give both repentance and remission of sins; and where he gives the one no doubt he gives the other. This fountain opened is the pierced side of Jesus Christ, spoken of just before (Zac 12:10), for thence came there out blood and water, and both for cleansing. And those who look upon Christ pierced, and mourn for their sins that pierced him, and are therefore in bitterness for him, may look again upon Christ pierced and rejoice in him, because it pleased the Lord thus to smite this rock, that it might be to us a fountain of living waters. See here, 1. How we are polluted; we are all so; we have sinned, and sin is uncleanness; it defiles the mind and conscience, renders us odious to God and uneasy in ourselves, unfit to be employed in the service of God and admitted into communion with him, as those who were ceremonially unclean were shut out of the sanctuary. The house of David and the inhabitants of Jerusalem are under sin, which is uncleanness. The truth is, we are all as an unclean thing, and deserve…

13:1-6 The second message (13:1-6) of the second oracle (chs 12–14) focuses on cleansing from sin. 13:1 A fountain is a spring of pure, flowing water for cleansing and purification (see 14:8; John 4:14; Rev 22:1-2). • God’s cleansing of Israel will include leaders (represented by the dynasty of David) and all the people of Judah and Israel (signified by the people of Jerusalem, the spiritual center of the nation). • to cleanse them: This cleansing, symbolized in the ritual washings of Old Testament worship (see Exod 30:17-21), was provided in the new covenant as promised by Jeremiah (Jer 31:34) and Ezekiel (Ezek 36:25; see Heb 10:1-22). • all their sins and impurity: The Hebrews would experience a complete moral and spiritual cleansing because of their sorrow over their sin (Zech 12:10-14).
