Zechariah 7:5
“Ask all the people of the land and the priests, ‘When you fasted and mourned in the fifth and seventh months for these seventy years, was it really for Me that you fasted?
Matthew 6:18
so that your fasting will not be obvious to men, but only to your Father, who is unseen. And your Father, who sees what is done in secret, will reward you.
