'Nazirite' in the Bible

because you [will] conceive and bear a son. No razor {will touch} his head, because the boy will be a {Nazirite of God} {from birth}. And it is he who will begin to deliver Israel from [the] hand of [the] Philistines."

And he said to me, 'Look, you [will] conceive and bear a son, so then, do not drink wine or strong drink, and do not eat anything unclean, for the boy will be a Nazirite of God from birth until the day of his death.'"

So {he confided everything to her}, and he said to her, "A razor {has never touched} my head, for I [am] a {Nazirite of God} {from birth}. If I am shaved my strength will leave me, and I will become weak, like everyone else.
