Zechariah 9:11

(r) As for thee also, by the blood of thy covenant I have sent forth thy (s) prisoners out of the pit in which [is] no water.

(r) Meaning Jerusalem, or the Church which is saved by the blood of Christ, of which the blood of the sacrifices was a figure. And it is here called the covenant of the Church, because God made it with his Church: and left it with them because of the love that he had for them.

(s) God shows that he will deliver his Church out of all dangers, no matter how great they may seem.
