Gittites
What Bible dictionaries say about “Gittites”, one article after the other.
International Standard Bible Encyclopedia (ISBE 1915)
git'-its (gittim, plural of gittiy): The inhabitants of Gath. They are mentioned along with the inhabitants of the other chief Philistine cities in Jos 13:3. It would seem that numbers of them emigrated to Judah, for we find 600 of them acting as a bodyguard to David with Ittai at their head (2Sa 15:18 ff; 18:2). Obed-edom, to whom David entrusted the ark when he was frustrated in bringing it into the city of David, was a Gittite (2Sa 6:11 f; 1Ch 13:13). The Gittites seem to have been remarkable for their great stature (2Sa 21:19; 1Ch 20:5).
