'Conceive' in the Bible

The angel of Yahweh appeared to the woman, and said to her, "See now, you are barren, and don't bear; but you shall conceive, and bear a son.

for, behold, you shall conceive, and bear a son; and no razor shall come on his head; for the child shall be a Nazirite to God from the womb: and he shall begin to save Israel out of the hand of the Philistines."

but he said to me, 'Behold, you shall conceive, and bear a son; and now drink no wine nor strong drink, and eat not any unclean thing; for the child shall be a Nazirite to God from the womb to the day of his death.'"
