With a sling and a stone David smote the Philistine giant (1 Sam. 17:40, 49). There were 700 Benjamites who were so skilled in its use that with the left hand they "could sling stones at a hair breadth, and not miss" (Judg. 20:16; 1 Chr. 12:2). It was used by the Israelites in war (2 Kings 3:25). (See ARMS.)

The words in Prov. 26:8, "As he that bindeth a stone in a sling," etc. (Authorized Version), should rather, as in the Revised Version, be "As a bag of gems in a heap of stones," etc.
