Take the special vow of a Nazirite, setting themselves apart to the Lord in a special way - Numbers 6:2
Nazirite had taken special vows of obedience to a set of rules that others didn't have to follow

Samuel served God and his poeple selflessly and faithfully
Only Samuel made a lasting impact for the Lord and his people
