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.
Berean Study Bible (BSB) - Numbers 6:21 >This is the law of the Nazirite who vows his offering to the LORD for his separation, in addition to whatever else he can afford; he must fulfill whatever vow he makes, according to the law of his separation.”
