1 Chronicles 20:3-5

The Voice

³ He set the people of the city to work with tools of iron: saws, axes and other sharp implements. This David did to all the Ammonite cities before he and his people returned to Jerusalem.

⁴ After David conquered Ammon, war erupted at the city of Gezer in Philistia. Sibbecai (the Hushathite) killed Sippai (a descendant of the giants) and subjugated the city. ⁵ During another Philistian encounter, Elhanan (son of Jair) killed Lahmi (brother of Goliath the Gittite) whose spear was as long as a weaver’s beam.
