Contradiction with Isaiah 2:4
Isaiah 2:4 describes a time of peace where swords are beaten into plowshares, in contrast to the emphasis on readiness for battle in Isaiah 5:28.
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 26:52
Matthew 26:52 emphasizes putting away the sword and warns that those who take the sword will perish by it, contradicting the notion of battle readiness in Isaiah 5:28.
Matthew 26:52: Thinkest thou that I cannot now pray to my Father, and he shall presently give me more than twelve legions of angels?
Contradiction with Micah 4:3
Similar to Isaiah 2:4, Micah 4:3 speaks of turning swords into plowshares and nations not learning war anymore, opposing the theme of military preparation in Isaiah 5:28.
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]
