Thus says the LORD of hosts; The fast of the fourth month, and the fast of the fifth, and the fast of the seventh, and the fast of the tenth, shall be to the house of Judah joy and gladness, and cheerful feasts; therefore love the truth and peace.

Athanasius the Apostolic

Therefore, when we come to the feast, we must not treat it as the shadows and pictures that Israel had, for they are fulfilled. Nor should we come to it as we would any ordinary secular feast. Oh, no! Let us go quickly to the Lord, who is himself the feast. We must not look at the feast as a time to delight the appetite and overindulge but as a display of virtue. The feasts of the heathen are made up of laziness and greed. They think idleness is the mark of a feast, and when they feast they do the despicable acts of death and hell. Our feasts, on the other hand, are scenes of virtuous activities and the practice of temperance. The prophetic word says it very clearly, “The fasts of the fourth, fifth, seventh and tenth months shall become feasts of joy and gladness for the house of Judah.”
Fast. They fasted on the ninth day of the fourth month, because on that day Nabuchodonosor took Jerusalem, Jeremias lii. 6. On the tenth day of the fifth month, because on that day the temple was burnt, Jeremias lii. 12. On the third day of the seventh month, for the murder of Godolias, Jeremias xli. 2. And on the tenth day of the tenth month, because on that day the Chaldeans began to besiege Jerusalem, 4 Kings xxv. 1. All these fasts, if they will be obedient for the future, shall be changed (as is here promised) into joyful solemnities. (Challoner)
They had only inquired about the fasts of the fifth and seventh months but the two others were also to be omitted in times of joy. (Worthington)
The Jews still observe all four. (Basnage v. 16.)
They fast on the seventeenth of the fourth month, because the breach was then made in the walls, (Calmet) and Moses broke the tables of the law, according to the Jews, in St. Jerome. The ninth of the fifth month is also kept instead of the tent...
The fast of the fourth month: They fasted, on the ninth day of the fourth month, because on that day Nabuchodonosor took Jerusalem, Jer. 52. 6. On the tenth day of the fifth month, because on that day the temple was burnt, Jer. 52. 12. On the third day of the seventh month, for the murder of Godolias, Jer. 41. 2. And on the tenth day of the tenth month, because on that day the Chaldeans began to besiege Jerusalem, 4 Kings 25. 1. All these fasts, if they will be obedient for the future, shall be changed, as is here promised, into joyful solemnities.
