2 Samuel 15:7-8

JPS_ASV_Byz(i) 7 And it came to pass at the end of forty years, that Absalom said unto the king: 'I pray thee, let me go and pay my vow, which I have vowed unto the LORD, in Hebron. 8 For thy servant vowed a vow while I abode at Geshur in Aram, saying: If the LORD shall indeed bring me back to Jerusalem, then I will serve the LORD.'
