And in the third, white horses; and in the fourth, horses of mixed colour.

And it came about in the fourth year of King Darius, that the word of the Lord came to Zechariah on the fourth day of the ninth month, the month Chislev.

This is what the Lord of armies has said: The times of going without food in the fourth month and in the fifth and the seventh and the tenth months, will be for the people of Judah times of joy and happy meetings; so be lovers of good faith and of peace.
