'Conceive' in the Bible

And the angel of the LORD appeared to the woman and said to her, "Behold, you are barren and have no children; but you shall conceive and bear a son.

for lo, you shall conceive and bear a son. No razor shall come upon his head, for the boy shall be a Nazirite to God from birth; and he shall begin to deliver Israel from the hand of the Philistines."

but he said to me, 'Behold, you shall conceive and bear a son; so then drink no wine or strong drink, and eat nothing unclean, for the boy shall be a Nazirite to God from birth to the day of his death.'"
