Zechariah 8:17-19

New Revised Standard Version, Anglicised Catholic Edition

¹⁷ do not devise evil in your hearts against one another, and love no false oath; for all these are things that I hate, says the Lord.

Joyful Fasting

¹⁸ The word of the Lord of hosts came to me, saying: ¹⁹ 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 seasons of joy and gladness, and cheerful festivals for the house of Judah: therefore love truth and peace.
