Bilangan 6:21

“Demikianlah peraturan-peraturan untuk pengabdi. Kalau seorang pengabdi berjanji untuk mempersembahkan kepada-Ku melebihi yang diwajibkan, dia harus menepatinya janjinya itu.”

This is the law of the Nazarite who hath vowed, and of his offering unto the LORD for his separation, beside that that his hand shall get: according to the vow which he vowed, so he must do after the law of his separation.
