Contradiction with Jeremiah 1:7
This verse contradicts Exodus 4:15 by indicating that God personally puts words directly into Jeremiah's mouth, whereas in Exodus 4:15, God instructs Moses to convey His words to Aaron.
Jeremiah 1:7: But the LORD said unto me, Say not, I [am] a child: for thou shalt go to all that I shall send thee, and whatsoever I command thee thou shalt speak.
Contradiction with Isaiah 55:11
This verse suggests that God's word accomplishes what He desires and prospers where He sends it, implying direct divine action without relying on human intermediaries as seen in Exodus 4:15.
Isaiah 55:11: So shall my word be that goeth forth out of my mouth: it shall not return unto me void, but it shall accomplish that which I please, and it shall prosper [in the thing] whereto I sent it.
Contradiction with 1 Corinthians 1:17
Paul states that Christ did not send him to baptize, but to preach the gospel, suggesting a different method of divine communication than the indirect method seen in Exodus 4:15.
1 Corinthians 1:17: For Christ sent me not to baptize, but to preach the gospel: not with wisdom of words, lest the cross of Christ should be made of none effect. [words: or, speech]
Contradiction with Acts 1:8
Here, the communication and witness is enabled directly by the Holy Spirit, contrasting with the intermediary arrangement in Exodus 4:15 where Moses speaks to Aaron.
Acts 1:8: But ye shall receive power, after that the Holy Ghost is come upon you: and ye shall be witnesses unto me both in Jerusalem, and in all Judaea, and in Samaria, and unto the uttermost part of the earth. [power...: or, the power of the Holy Ghost coming upon you]
Contradiction with Matthew 10:19-20
Jesus tells his disciples that the Spirit will speak through them directly, whereas Exodus 4:15 indicates Moses speaks through Aaron.
Matthew 10:19-20: But when they deliver you up, take no thought how or what ye shall speak: for it shall be given you in that same hour what ye shall speak.
Paradox #1
Exodus 4:15 might present a contradiction if one considers the broader context of free will versus divine control. The verse implies that God tells Moses what to say, which could be seen as conflicting with the idea of humans having free will to choose their own words and actions. This tension between divine instruction and human autonomy can be viewed as a moral inconsistency.
