Contradiction with Matthew 5:9
This verse speaks about the blessedness of peacemakers, while Jeremiah 47:6 talks about a sword that does not rest.
Matthew 5:9: Blessed [are] the peacemakers: for they shall be called the children of God.
Contradiction with Romans 12:18
This verse encourages living peaceably with all men, contrasting with the unrest in Jeremiah 47:6.
Romans 12:18: If it be possible, as much as lieth in you, live peaceably with all men.
Contradiction with Isaiah 2:4
This verse foresees a time when nations will beat swords into plowshares, which contradicts the ongoing sword in Jeremiah 47:6.
Isaiah 2:4: And he shall judge among the nations, and shall rebuke many people: and they shall beat their swords into plowshares, and their spears into pruninghooks: nation shall not lift up sword against nation, neither shall they learn war any more. [pruninghooks: or, scythes]
Contradiction with Micah 4:3
Similar to Isaiah 2:4, this verse envisions peace and the end of war, opposing the image in Jeremiah 47:6.
Micah 4:3: And he shall judge among many people, and rebuke strong nations afar off; and they shall beat their swords into plowshares, and their spears into pruninghooks: nation shall not lift up a sword against nation, neither shall they learn war any more. [pruninghooks: or, scythes]
Contradiction with Psalm 46:9
This verse describes God making wars cease and breaking the bow, a direct contradiction to the active sword in Jeremiah 47:6.
Psalm 46:9: He maketh wars to cease unto the end of the earth; he breaketh the bow, and cutteth the spear in sunder; he burneth the chariot in the fire.
