Contradiction with Exodus 4:10
Moses expresses reluctance to speak due to being slow of speech and tongue, similar to Jeremiah's excuse of being unable to speak due to youth, but God assures Moses He will help him speak.
Exodus 4:10: And Moses said unto the LORD, O my Lord, I [am] not eloquent, neither heretofore, nor since thou hast spoken unto thy servant: but I [am] slow of speech, and of a slow tongue. [eloquent: Heb. a man of words] [heretofore: Heb. since yesterday, nor since the third day]
Contradiction with Isaiah 6:5-7
Isaiah expresses inadequacy and unworthiness, yet God addresses his concern immediately by cleansing him, in contrast to Jeremiah's initial excuse.
Isaiah 6:5-7: Then said I, Woe [is] me! for I am undone; because I [am] a man of unclean lips, and I dwell in the midst of a people of unclean lips: for mine eyes have seen the King, the LORD of hosts. [undone: Heb. cut off]
Contradiction with 1 Timothy 4:12
Paul advises Timothy not to let anyone despise his youth but to be an example; contradicts Jeremiah's concern about being too young to speak.
1 Timothy 4:12: Let no man despise thy youth; but be thou an example of the believers, in word, in conversation, in charity, in spirit, in faith, in purity.
Contradiction with Jonah 1:1-3
Jonah attempts to flee from God's calling because of reluctance, whereas Jeremiah voices inability due to his age.
Jonah 1:1-3: Now the word of the LORD came unto Jonah the son of Amittai, saying, [Jonah: Gr. Jonas]
Contradiction with Numbers 22:28
God enables even a donkey to speak, suggesting that age or speech capability should not hinder fulfilling God's command, contrasting with Jeremiah's hesitation.
Numbers 22:28: And the LORD opened the mouth of the ass, and she said unto Balaam, What have I done unto thee, that thou hast smitten me these three times?
