“Those who hammer their guns into plows will plow for those who do not”

“They shall beat their swords into plowshares, and their spears into pruning hooks” is from the Book of Isaiah. The saying has been used by anti-war groups. A pro-gun saying is, “Those who hammer their guns into plows will plow for those who do not.”
 
“Those who hammer their guns into plows, will plow for those who don’t” has been cited in print since at least 1997, when it appeared in The Free American!. By at least 2007, the saying was credited to Thomas Jefferson (1743-1826), who never said it.
 
 
Wikipedia: Swords to ploughshares
Swords to ploughshares (or swords to plowshares) is a concept in which military weapons or technologies are converted for peaceful civilian applications.
 
The phrase originates from the Book of Isaiah:
 
And many people shall go and say, Come ye, and let us go up to the mountain of the Lord, to the house of the God of Jacob; and he will teach us of his ways, and we will walk in his paths: for out of Zion shall go forth the law, and the word of the Lord from Jerusalem. And he shall judge among the nations, and shall rebuke many people: and they shall beat their swords into plowshares, and their spears into pruning hooks: nation shall not lift up sword against nation, neither shall they learn war any more. — Isaiah 2:3-4
