English Standard Version
Chapter 15 7
And at the end of four years Absalom said to the king, “Please let me go and pay my vow, which I have vowed to the LORD, in Hebron. 8
For your servant vowed a vow while I lived at Geshur in Aram, saying, ‘If the LORD will indeed bring me back to Jerusalem, then I will offer worship to the LORD.’” 9
The king said to him, “Go in peace.” So he arose and went to Hebron.
