STONES, pieces of rock of any shape, usually detached from bedrock and of no great size, as in stream beds (1 Sam 17:40). They have been much used by man for various constructional purposes (e.g. Gen 35:14). Unless separated by human activity, such as quarrying (1 Chron 22:15), stones are detached from bedrock and shaped by the action of various processes of weathering, such as frost and running water. The term “stone” is commonly used as a synonym for “rock,” particularly where man has put it to some practical purpose. It is also used with reference to ores in mineral deposits (Deut 8:9), in relation to ground water bearing acquifers (Num 20:11) and to gems—precious stones (q.v. jewels and precious stones).
