Ithai, also called Ittai, is the name of two men associated with David. One was a Benjamite from Gibeah and one of David’s heroes. The other was a Gittite from Gath and a leading commander among David’s followers.
The Gittite Ittai remained loyal to David during Absalom’s rebellion, refusing to return to Jerusalem and share the new king’s service. David later appointed him a chief captain alongside Joab and Abishai.
The Benjamite Ithai served in David’s guard about 1046 B.C. The Gittite appears to have recently left Gath and joined David’s army out of personal loyalty.
