2 Samuel 15:20-21

20You came only yesterday, so should I make you wander with us today while I go where I will? Return and take your brothers back with you also. May lovingkindness and faithfulness be with you.”

21But Ittai answered the king, “As the Lord lives, and as my lord the king lives, most certainly wherever my lord the king may be, whether for death or life, there will your servant be also.”
