David went out to meet them and said to them, “If you have come in peace to help me, my heart will be united with you, but if you have come to betray me to my enemies even though my hands have done no wrong, may the God of our ancestors look on it and judge.”

From the Hebronites: Jerijah was the head of the Hebronites, according to the genealogical records of his ancestors. A search was made in the fortieth year of David’s reign and strong, capable men were found among them at Jazer in Gilead.

For we live before You as foreigners and temporary residents in Your presence as were all our ancestors. Our days on earth are like a shadow, without hope.

Lord God of Abraham, Isaac, and Israel, our ancestors, keep this desire forever in the thoughts of the hearts of Your people, and confirm their hearts toward You.

Then David said to the whole assembly, “Praise the Lord your God.” So the whole assembly praised the Lord God of their ancestors. They bowed down and paid homage to the Lord and the king.
