The Prophet Isaiah urges the people to “beat their swords into plowshares” and learn war no more (700s BC)
Found in: The Book of the Prophet Isaiah (KJV)
The Gospels draw heavily on the Book of Isaiah for a utopic view of the world. The famous “swords to plowshares” quote is but one of its famous proclamations:
Religion & Toleration
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. (Isaiah 2:4).
