A time to cast away stones— This is differently understood. Calmet says, it may either signify, "a time to cast away stones with a sling, and a time to collect them again into a bag:" or, "A time to cast stones on a field to render it barren, and a time to collect the stones out of a field to render it fertile." See 2 Kings 3:25. Or, "A time to cast away improper, and to collect proper stones for building." See Ecclesiastes 3:3.
