Contradiction with Proverbs 16:1
This verse suggests that preparation of the heart is from man, while Matthew 10:19 implies reliance on Divine guidance in speech.
Proverbs 16:1: The preparations of the heart in man, and the answer of the tongue, [is] from the LORD. [preparations: or, disposings]
Contradiction with Proverbs 21:5
This verse emphasizes the importance of diligent planning, contrary to the directive in Matthew 10:19 not to plan what to say.
Proverbs 21:5: The thoughts of the diligent [tend] only to plenteousness; but of every one [that is] hasty only to want.
Contradiction with 1 Peter 3:15
This verse advises believers to always be prepared to explain their faith, conflicting with the instruction of not premeditating responses in Matthew 10:19.
1 Peter 3:15: But sanctify the Lord God in your hearts: and [be] ready always to [give] an answer to every man that asketh you a reason of the hope that is in you with meekness and fear: [fear: or, reverence]
Contradiction with Isaiah 50:4
This verse highlights the role of a well-instructed tongue, suggesting preparation, whereas Matthew 10:19 advises against pre-planning speech.
Isaiah 50:4: The Lord GOD hath given me the tongue of the learned, that I should know how to speak a word in season to [him that is] weary: he wakeneth morning by morning, he wakeneth mine ear to hear as the learned.
Contradiction with Luke 12:11-12
Although similar, the subtle difference implies a slight contradiction, as Luke specifies the Holy Ghost's role distinctly, whereas Matthew is more general.
Luke 12:11-12: And when they bring you unto the synagogues, and [unto] magistrates, and powers, take ye no thought how or what thing ye shall answer, or what ye shall say:
Paradox #1
Some people might see a conflict between Matthew 10:19 and the idea of preparation and study in religious teachings. This verse suggests trusting in divine guidance for what to say rather than planning ahead. This could seem inconsistent with teachings that encourage learning and preparing in other parts of religious life. However, many believe this guidance applies specifically to moments of persecution or testimony, not to all aspects of life.
