拿细耳人（希伯来语: נזיר，nazir，意为“神圣的”或“分开的”）是指根据《圣经》记载“归耶和华为圣”（民数记6章8节）的以色列男女。

哈拉卡在拿细耳人的条例方面有丰富的传统。这些条例首先记载在密西拿和 塔木德。根据犹太教正统派的观点，这些条例并未成为历史陈迹，甚至今天仍可实行。但是由于今天已经没有耶路撒冷圣殿用于完成誓约，而任何誓约都是永久的，现代的犹太教权威人士强烈阻碍实行该点。

所有誓约的条例通常都可以应用于拿细耳人的誓约。和其他誓约一样，父亲有权废除年轻女儿的拿细耳人誓约，丈夫有权废除妻子的誓约，但是这样的废除誓约必须在首次听到时实施。不得在当时保持静默，过了一些时日后才废除。 拿细耳人起的特别誓约如下：

In the Hebrew Bible, a nazirite or nazarite is one who voluntarily took a vow described in Numbers 6:1–21. "Nazarite" comes from the Hebrew word נזיר nazir meaning "consecrated" or "separated". This vow required the person to:

After following these requirements for a designated interval (which would be specified in the individual's vow), the person would immerse in a mikveh and make three offerings: a lamb as a burnt offering (olah), an ewe as a sin-offering (hatat), and a ram as a peace offering (shelamim), in addition to a basket of unleavened bread, grain offerings and drink offerings, which accompanied the peace offering. They would also shave their head in the outer courtyard of the Temple (the Jerusalem Temple) and then place the hair on the same fire as the peace offering. (Numbers 6:18)
