Contradiction with 1 Samuel 8:5
This verse contradicts Exodus 18:21 by expressing the people's desire for a king to judge them, contrasting the earlier system of appointing capable men described in Exodus.
1 Samuel 8:5: And said unto him, Behold, thou art old, and thy sons walk not in thy ways: now make us a king to judge us like all the nations.
Contradiction with Hosea 13:10-11
These verses show God's displeasure with Israel wanting a king, contrary to the system of governance by capable men set in Exodus 18:21.
Hosea 13:10-11: I will be thy king: where [is any other] that may save thee in all thy cities? and thy judges of whom thou saidst, Give me a king and princes? [I will...: rather, Where is thy king?]
Contradiction with Matthew 20:25-26
These verses advocate for servant leadership rather than the authoritative selection of capable men in positions of power, as suggested in Exodus 18:21.
Matthew 20:25-26: But Jesus called them [unto him], and said, Ye know that the princes of the Gentiles exercise dominion over them, and they that are great exercise authority upon them.
Contradiction with Ezekiel 34:2
This verse criticizes leaders who fail to shepherd the people adequately, contrasting with Exodus 18:21 which supports appointing leaders from among the people.
Ezekiel 34:2: Son of man, prophesy against the shepherds of Israel, prophesy, and say unto them, Thus saith the Lord GOD unto the shepherds; Woe [be] to the shepherds of Israel that do feed themselves! should not the shepherds feed the flocks?
Paradox #1
Exodus 18:21 could present a contradiction or inconsistency in that it suggests a system of hierarchy and leadership based on certain criteria. This might conflict with other biblical teachings that promote equality and humility, where no one is considered greater than another. This can create tension between the idea of structured leadership and the principle of universal equality.
