2 Samuel 15:7-10

7After four years, Absalom said to the king, ‘Please let me go to Hebron. I need to make a sacrifice to the Lord, as I promised to do.

8When I was living at Geshur with the Arameans, I made this promise: “If the Lord brings me back to live in Jerusalem, I will go to Hebron and I will worship him there.” ’

9The king said, ‘Yes, you may go.’ So Absalom left Jerusalem and he went to Hebron.

10Then Absalom sent his men to go secretly to all the tribes of Israel. They took this message to the people: ‘When you hear the noise of trumpets, then you must shout, “Absalom has become king in Hebron.” ’
