'Dedicated' in the Bible

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."

He told me, "Surprise! you're going to conceive and give birth to a son!' and as for you, "Be sure that you don't drink wine or anything intoxicating, and don't eat anything unclean,' "because the young man will be a Nazirite dedicated to God from inside the womb' until the day he dies."
