Contradiction with Isaiah 43:10
Contradicts by asserting that no other gods exist besides the LORD, whereas Isaiah 43:9 implies the presence of other "people" who need to be gathered and proven right.
Isaiah 43:10: Ye [are] my witnesses, saith the LORD, and my servant whom I have chosen: that ye may know and believe me, and understand that I [am] he: before me there was no God formed, neither shall there be after me. [no...: or, nothing formed of God]
Contradiction with 1 Corinthians 8:5-6
Acknowledges the presence of many gods and lords but affirms there is only one God for Christians, contrary to the exclusive divine testimony role in Isaiah 43:9.
1 Corinthians 8:5-6: For though there be that are called gods, whether in heaven or in earth, (as there be gods many, and lords many,)
Contradiction with Deuteronomy 4:35
Contradicts by stating there is none other besides God, while Isaiah 43:9 calls for other nations to testify and be justified.
Deuteronomy 4:35: Unto thee it was shewed, that thou mightest know that the LORD he [is] God; [there is] none else beside him.
Contradiction with Exodus 20:3
Declares explicitly to have no other gods, whereas Isaiah 43:9 entertains the idea of gathering peoples and proving them right.
Exodus 20:3: Thou shalt have no other gods before me.
Paradox #1
The verse suggests a gathering of nations and peoples to validate the truth of a prophecy or event. A possible contradiction or inconsistency could arise if there is no historical record or evidence of such a global gathering occurring as described. Essentially, there might be a conflict with historical events or records that do not align with this depiction.
