Contradiction with 1 John 1:5
Luke 1:22 talks about Zacharias becoming unable to speak, which could symbolize silence or darkness, while 1 John 1:5 states that "God is light, and in him is no darkness at all."
1 John 1:5: This then is the message which we have heard of him, and declare unto you, that God is light, and in him is no darkness at all.
Contradiction with Proverbs 17:27
This proverb highlights the wisdom in someone who spares their words, which might seem contrary to the negative consequence seen in Luke 1:22, where silence is a punishment rather than an indicator of wisdom.
Proverbs 17:27: He that hath knowledge spareth his words: [and] a man of understanding is of an excellent spirit. [an...: or, a cool]
Contradiction with James 3:2
James 3:2 suggests that not offending in word is a sign of perfection, which contradicts with the implication in Luke 1:22, where Zacharias's lack of speech is a direct result of disbelief, not perfection.
James 3:2: For in many things we offend all. If any man offend not in word, the same [is] a perfect man, [and] able also to bridle the whole body.
