Contradiction with Isaiah 2:4
Unlike Revelation 9:14, which speaks of releasing angels bound at the Euphrates for destruction, Isaiah 2:4 envisions a time of peace where nations beat swords into plowshares and study war no more.
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 Matthew 5:9
Jesus calls peacemakers blessed and children of God, contrasting with the angels of destruction released in Revelation 9:14.
Matthew 5:9: Blessed [are] the peacemakers: for they shall be called the children of God.
Contradiction with Jeremiah 29:11
Promises peace and hope, which contradicts the destructive element associated with Revelation 9:14.
Jeremiah 29:11: For I know the thoughts that I think toward you, saith the LORD, thoughts of peace, and not of evil, to give you an expected end. [expected...: Heb. end and expectation]
Contradiction with Romans 12:18
Encourages living peaceably with all, opposite to the implied conflict and destruction in Revelation 9:14.
Romans 12:18: If it be possible, as much as lieth in you, live peaceably with all men.
Contradiction with Psalms 46:9
God makes wars cease and shatters weapons, which contrasts with the notion of war implied in Revelation 9:14.
Psalms 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.
Contradiction with 1 Thessalonians 5:3
Describes peace and safety before sudden destruction, which contrasts with the predetermined release leading to destruction as seen in Revelation 9:14.
1 Thessalonians 5:3: For when they shall say, Peace and safety; then sudden destruction cometh upon them, as travail upon a woman with child; and they shall not escape.
Paradox #1
The potential contradiction or conflict could be the idea of a loving and forgiving God allowing or commanding such devastating consequences or suffering. This can seem inconsistent with other teachings about God's nature being compassionate and just.
