'Conceive' in the Bible

The Lord's angelic messenger appeared to the woman and said to her, "You are infertile and childless, but you will conceive and have a son.

Look, you will conceive and have a son. You must never cut his hair, for the child will be dedicated to God from birth. He will begin to deliver Israel from the power of the Philistines."

He said to me, 'Look, you will conceive and have a son. So now, do not drink wine or beer and do not eat any food that will make you ritually unclean. For the child will be dedicated to God from birth till the day he dies.'"
