Contradiction with Numbers 23:19
This verse says God is not a man that He should lie or change His mind, which challenges the idea that there should be contradicting instructions or changes within His commandments.
Numbers 23:19: God [is] not a man, that he should lie; neither the son of man, that he should repent: hath he said, and shall he not do [it]? or hath he spoken, and shall he not make it good?
Contradiction with 1 Corinthians 14:33
This verse states that God is not the author of confusion, yet the specificity of Exodus 25:35 might seem confusing if considered alongside other non-detailed descriptions.
1 Corinthians 14:33: For God is not [the author] of confusion, but of peace, as in all churches of the saints. [confusion: Gr. tumult, or, unquietness]
