Hacer el amor y no la guerra / Fumar la pipa de la paz
You beat your swords into plowshares when you decide to stop fighting and to devote your time to more constructive affairs.
It comes from the Bible, Isaiah 2:4 where the following expression appears, “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.” Swords and spears are war artifacts. To turn them into farming tools, such as plowshares and pruning hooks means to devote our time into peaceful affairs and to forget about war. A clear example of the use of this expression in modern times is when a country decides that a manufacturing company that used to produce war tanks will now make farm tractors.
