。。。that God interposes and takes the part of his Church against Satan. Hence he says, Rebuke thee Satan let Jehovah,1 rebuke thee let Jehovah, who has chosen Jerusalem. God speaks here; and yet he seems to be the angel of Jehovah:2 but this is not inscrutable; for a in the last verse, where Zechariah says that Joshua stood before the angel of Jehovah, Christ is doubtless meant, who is called an angel and also Jehovah; so also he may be named in this verse.
But that no contentious person may say that we refine on the words too much, we may take them simply thus,—that God mentions here his own name in the third person; and this mode of speaking is not rare in Scripture, “Jehovah rained from God.” (Gen. 19:24.) Why did Moses speak thus? Even to show that when God fulminated against Sodom, he did not adopt a common mode of proceeding, but openly showed that it was an unusual and a singular judgment. Thus the expression here is emphatic, Rebuke thee let Jehovah, that is, I myself will rebuke thee.
However, were any one to consider well the whole context, he could not but allow that the words may properly be applied to Christ, who is the portion of his Church, and that therefore he was the angel before whom Joshua stood; and he himself shows afterwards that the Church would be safe under his patronage.

[2] But the orthodox doctors of the church have rightly and prudently interpreted that chief angel to be God’s Word, who already at that time, as a sort of foretaste, began to fulfill the office of Mediator.29 For even though he was not yet clothed with flesh, he came down, so to speak, as an intermediary, in order to approach believers more intimately.
