Contradiction with Matthew 27:14
Jesus remained silent when accused, which contrasts with Luke 19:40 where there would be proclamation if His disciples were silent.
Matthew 27:14: And he answered him to never a word; insomuch that the governor marvelled greatly.
Contradiction with Ecclesiastes 3:7
This verse speaks to a time to keep silence, contrasting Luke 19:40 where silence by disciples leads to the stones crying out.
Ecclesiastes 3:7: A time to rend, and a time to sew; a time to keep silence, and a time to speak;
Contradiction with Proverbs 10:19
Advises against excessive talking, contradicting the idea in Luke 19:40 where even in silence, proclamation is inevitable.
Proverbs 10:19: In the multitude of words there wanteth not sin: but he that refraineth his lips [is] wise.
Contradiction with James 1:19
Advises being slow to speak, which contrasts with the implied immediate proclamation when disciples are silent in Luke 19:40.
James 1:19: Wherefore, my beloved brethren, let every man be swift to hear, slow to speak, slow to wrath:
Contradiction with Isaiah 53:7
Depicts the Messiah as silent before His oppressors, whereas Luke 19:40 implies proclamation even in the absence of disciples' voices.
Isaiah 53:7: He was oppressed, and he was afflicted, yet he opened not his mouth: he is brought as a lamb to the slaughter, and as a sheep before her shearers is dumb, so he openeth not his mouth.
Paradox #1
The contradiction could be that the verse suggests a kind of inevitability or necessity of praise or proclamation, potentially conflicting with the belief in free will. If people are compelled to give praise and do not, the suggestion that nature or other entities would instead might seem to undermine the concept of choice. This could lead to questions about the balance between divine will and human freedom.
