Then the king said to Ittai the Gittite, “Why should you come with us? Go back and stay with the new ¹  king, for you are a foreigner and an exile from your own country. ² 

So David was no longer willing to bring the ark of the Lord to be with him in the City of David. David left it in the house of Obed-Edom the Gittite.

The ark of the Lord remained in the house of Obed-Edom the Gittite for three months. The Lord blessed Obed-Edom and all his family. ¹ 

So David said to Ittai, “Come along then.” ¹  So Ittai the Gittite went along, ²  accompanied by all his men and all the dependents ³  who were with him.

So David did not move the ark to the City of David; ¹  he left it in the house of Obed-Edom the Gittite.

There was another battle with the Philistines in which Elhanan son of Jair the Bethlehemite killed the brother of Goliath the Gittite, ¹  whose spear had a shaft as big as the crossbeam of a weaver’s loom. ² 

All his servants were leaving with him, ¹  along with all the Kerethites, all the Pelethites, and all the Gittites – some six hundred men who had come on foot from Gath. They were leaving with ²  the king.

Yet another battle occurred with the Philistines in Gob. On that occasion Elhanan the son of Jair ¹  the Bethlehemite killed the brother of Goliath the Gittite, ²  the shaft of whose spear was like a weaver’s beam.

David then sent out the army – a third under the leadership of Joab, a third under the leadership of Joab’s brother Abishai son of Zeruiah, and a third under the leadership of Ittai the Gittite. The king said to the troops, “I too will indeed march out with you.”

from the Shihor River ¹  east of ²  Egypt northward to the territory of Ekron (it is regarded as Canaanite territory), ³  including the area belonging to the five Philistine lords who ruled in Gaza, Ashdod, Ashkelon, Gath, and Ekron, as well as Avvite land ⁴ 

But Ittai replied to the king, “As surely as the Lord lives and as my lord the king lives, wherever my lord the king is, whether dead or alive, ¹  there I ²  will be as well!”
