Contradiction with Matthew 6:16
This verse advises against showing outward signs of fasting for the sake of appearances, while Zechariah 8:19 acknowledges specific fasts as moments of joy and cheerfulness.
Matthew 6:16: Moreover when ye fast, be not, as the hypocrites, of a sad countenance: for they disfigure their faces, that they may appear unto men to fast. Verily I say unto you, They have their reward.
Contradiction with Isaiah 58:3-4
These verses criticize hypocritical fasting that leads to disputes, in contrast to the transformation of fasts into joyful occasions in Zechariah 8:19.
Isaiah 58:3-4: Wherefore have we fasted, [say they], and thou seest not? [wherefore] have we afflicted our soul, and thou takest no knowledge? Behold, in the day of your fast ye find pleasure, and exact all your labours. [labours: or, things wherewith ye grieve others: Heb. griefs]
Contradiction with Matthew 9:14-15
These verses indicate a time when fasting is not appropriate due to Jesus' presence, whereas Zechariah 8:19 turns traditional fasts into occasions for joy.
Matthew 9:14-15: Then came to him the disciples of John, saying, Why do we and the Pharisees fast oft, but thy disciples fast not?
Contradiction with Joel 2:12-13
These verses call for a sincere, heart-felt return to God through fasting, yet Zechariah 8:19 promotes fasting days as times of celebration.
Joel 2:12-13: Therefore also now, saith the LORD, turn ye [even] to me with all your heart, and with fasting, and with weeping, and with mourning:
Contradiction with Luke 18:12
Here, fasting is a personal discipline observed twice a week, while Zechariah 8:19 speaks of transforming set fasts into joyful feasts.
Luke 18:12: I fast twice in the week, I give tithes of all that I possess.
Paradox #1
Zechariah 8:19 mentions specific fasts turning into joyful occasions for the people. A possible contradiction or inconsistency could be with other parts of the Bible that emphasize fasting as a solemn time for reflection and repentance. This shift from fasting to joy might seem at odds with traditional views on the purpose of fasting in other scriptural contexts, where fasting is usually associated with mourning or seeking forgiveness.
