'Hair of His Head' in the Bible

'All days of the vow of his separation a razor doth not pass over his head; till the fulness of the days which he doth separate to Jehovah he is holy; grown up hath the upper part of the hair of his head.

And the hair of his head beginneth to shoot up, when he hath been shaven,

And the people say unto Saul, 'Doth Jonathan die who wrought this great salvation in Israel? -- a profanation! Jehovah liveth, if there falleth from the hair of his head to the earth, for with God he hath wrought this day;' and the people rescue Jonathan, and he hath not died.

and in his polling his head -- and it hath been at the end of year by year that he polleth it, for it is heavy on him, and he hath polled it -- he hath even weighed out the hair of his head -- two hundred shekels by the king's weight.

I was seeing till that thrones have been thrown down, and the Ancient of Days is seated, His garment as snow is white, and the hair of his head is as pure wool, His throne flames of fire, its wheels burning fire.
