The angel of the Lord prophesied about Samson and gave instructions to Samson's mother. Samson's mother was to offer up her son under a Nazarite vow. This was a special type of vow, dedicating Samson to Yahweh. Part of this vow prohibited the cutting of the person's hair. (See: [[rc://en/tw/dict/bible/kt/prophet]] and [[rc://en/tw/dict/bible/kt/vow]])
