1 sn If it was obvious to the soldiers that the victim was already dead it is difficult to see why one of them would try to inflict a wound. The Greek verb pierced (νύσσω, nussw) can indicate anything from a slight prod to a mortal wound. Probably one of the soldiers gave an exploratory stab to see if the body would jerk. If not, he was really dead. This thrust was hard enough to penetrate the side, since the author states that blood and water flowed out immediately.
2 sn How is the reference to the blood and water that flowed out from Jesus’ side to be understood? This is probably to be connected with the statements in 1 John 5:6-8. In both passages water, blood, and testimony are mentioned. The Spirit is also mentioned in 1 John 5:7 as the source of the testimony, while here the testimony comes from one of the disciples (19:35). The connection between the Spirit and the living water with Jesus’ statement of thirst just before he died in the preceding context has already been noted (see 19:28). For the author, the water which flowed out of Jesus’ side was a symbolic reference to the Holy Spirit who could now be given because Jesus was now glorified (cf. 7:39); Jesus had now departed and returned to that glory which he had with the Father before the creation of the world (cf. 17:5). The mention of blood recalls the motif of the Passover lamb as a sacrificial victim. Later references to sacrificial procedures in the Mishnah appear to support this: m. Pesahim 5:3 and 5:5 state that the blood of the sacrificial animal should not be allowed to congeal but should flow forth freely at the instant of death so that it could be used for sprinkling; m. Tamid 4:2 actually specifies that the priest is to pierce the heart of the sacrificial victim and cause the blood to come forth.
3 sn A quotation from Zech 12:10. Here a single phrase is quoted from Zech 12, but the entire context is associated with the events surrounding the crucifixion. The “Spirit of grace and of supplication” is poured out on the house of David and the inhabitants of Jerusalem in the first part of v. 10. A few verses later in 13:1 Yahweh (typically rendered as “Lord” in the OT) says “In that day a fountain will be opened for the house of David and for the inhabitants of Jerusalem, for sin and for impurity.” The blood which flowed from Jesus’ pierced side may well be what the author saw as the connection here, since as the shedding of the blood of the sacrificial victim it represents cleansing from sin. Although the Jewish authorities and Roman soldiers certainly “looked on the one whom they have pierced” as he hung on the cross, the author may also have in mind the parousia (second coming) here. The context in Zech 12-14 is certainly the second coming, so that these who crucified Jesus will look upon him in another sense when he returns in judgment.
