'Conceive' in the Bible

Then the angel of the Lord appeared to the woman and said to her, “Behold now, you are barren and have borne no children, but you shall conceive and give birth to a son.

For behold, you shall conceive and give birth to a son, and no razor shall come upon his head, for the boy shall be a Nazirite to God from the womb; and he shall begin to deliver Israel from the hands of the Philistines.”

But he said to me, ‘Behold, you shall conceive and give birth to a son, and now you shall not drink wine or strong drink nor eat any unclean thing, for the boy shall be a Nazirite to God from the womb to the day of his death.’”
