'Razor' in the Bible

During the entire time of his dedication, he is not to allow a razor to pass over his head until the days of his holy consecration to the LORD have been fulfilled. He is to let the locks on his head grow long.

'And thus thou dost to them to cleanse them: sprinkle upon them waters of atonement, and they have caused a razor to pass over all their flesh, and have washed their garments, and cleansed themselves,

because surprise! you're going to conceive and give birth to a son! Don't put a razor to his head, because the young man will be a Nazirite, dedicated to God from inside the womb. He will begin to deliver Israel from domination by the Philistines."

So he finally disclosed everything. He told her, "A razor has never touched my head, because I've been a Nazirite for God before I was born. If I am shaved, then my strength will abandon me and I will become weak like every human being."

Hannah made a vow: "LORD of the Heavenly Armies, if you just look at the misery of your maid servant, remember me, and don't forget your maid servant. If you give your maid servant a son, then I'll give him to the LORD for all the days of his life, and a razor is never to touch his head."

Like a sharpened razor,your tongue devises destruction,working treachery.

On that day the Lord will use a razor hired from beyond the Euphrates River—the king of Assyria—to shave the head, the hair on the legs, and to remove the beard as well.

“Now you, son of man, take a sharp sword, use it as you would a barber’s razor, and shave your head and beard. Then take a set of scales and divide the hair.
