swords to ploughshares

1. The notion of converting military forces, technologies, or ideas into peaceful purposes. A shortening of the phrase "beat swords into ploughshares" from the Bible. (Spelled "plowshare" in American English.) Primarily heard in UK. The program aims to collect disused or surplus military equipment and put them to use in public health clinics in developing countries—swords to ploughshares, if you will.

2. By extension, the abstention from destructive activities, such as war and violence, in favor of peaceful, constructive activities. We must adopt a swords-to-ploughshares mentality if our children are ever to inherit a world worth living in.
