'Pregnant' in the Bible

And the Angel of the Lord appeared to the woman and said to her, “Behold, you are infertile and have no children, but you shall conceive and give birth to a son.

For behold, you shall conceive and give birth to a son. No razor shall come upon his head, for the boy shall be a Nazirite [dedicated] to God from birth; and he shall begin to rescue 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 [any other] intoxicating drink, nor eat anything [ceremonially] unclean, for the boy shall be a Nazirite to God from birth to the day of his death.’”
