'Hair of His Head' in the Bible

All the days of the vow of his consecration a razor shall not pass over upon his head: till the filling up of the days which he shall consecrate to Jehovah, he shall be holy, increasing the locks of the hair of his head.

And the hair of his head will begin to grow as when he was shaven.

And the people will say to Saul, Shall Jonathan die, who did this great salvation in Israel? Far be it: Jehovah lives if there shall fall from the hair of his head to the earth; for he did with Jehovah this day. And the people will let Jonathan go free, and he died not.

And in his shaving his head (and it was from the end of days to days that he will shave, for it was heavy upon him;) and he shaved and weighed the hair of his head, two hundred shekels by the stone of the king.

I was seeing even till thrones were cast down, and the Ancient of days sat, his garment white as snow, and the hair of his head as pure wool: his throne a flame of fire, his wheels a burning fire.
