A striking tool. The earliest hammers were simply smooth or shaped stones. Beginning in the Bronze Age, stones were hallowed out to give a better grip or to receive a handle. Mallets of bone and wood were used (Judges 5:26), though these have not normally been preserved. Hammers with metal heads were rare in Palestine, possibly because metal was reserved for tools needing a cutting edge.
Hammers were used in cutting stone (1 Kings 6:7), working common and precious metals (Isaiah 41:7;
Isaiah 44:12), and for woodworking (Jeremiah 10:4). A hammer-like weapon was also used in battle (Jeremiah 51:20 “shatterer” NAS margin;
Ezekiel 9:2 “shattering weapon”). See Arms and Armor.
The hammer was a symbol of power. God's word is pictured as a hammer (Jeremiah 23:29). Babylon is mocked as a hammer whose strength has failed (Jeremiah 50:23). See Tools.
