Zechariah 6:2

“In the first chariot [were] red horses, etc.] If these are to be understood of the apostles of Christ, and ministers of the Gospel, they may be compared to “horses”, for bearing the name of Christ, and drawing the chariot of the Gospel; for their strength to labour in the word and doctrine; for their courage in the cause of Christ; and for their swiftness in doing his work; and to “red” ones, for their flaming zeal for the honour of the Redeemer, and their bloody sufferings for his sake: and if of angels, they may be compared to “horses”, because strong and swift to do the will of God; and to “red” ones, because they are the executioners of his wrath and vengeance on wicked men: but if by…”
