2 Samuel 15:21-25

But Ittai answered the king and said, “As the Lord lives, and as my lord the king lives, wherever my lord the king may be, whether for death or for life, there assuredly shall your servant be!”

Then David said to Ittai, “Go and cross over the brook Kidron.” So Ittai the Gittite crossed over with all his men and all the little ones who were with him.

While all the country was weeping with a loud voice, all the people were crossing over. The king was also crossing over the brook Kidron, and all the people were crossing over toward the way of the wilderness.

Now behold, Zadok also came, and all the Levites with him, carrying the ark of the covenant of God. And they set down the ark of God, and Abiathar came up until all the people had finished crossing over from the city.

And the king said to Zadok, “Return the ark of God to the city. If I find favor in the sight of the Lord, then He will bring me back and show me both it and His habitation.
