Samson's birth foretold
The angel of Yahweh told Manoah's barren wife that she would bear a son, a Nazirite from birth, who would begin to save Israel from the Philistines.
for, behold, you shall conceive and give birth to a son. No razor shall come on his head, for the child shall be a Nazirite to God from the womb. He shall begin to save Israel out of the hand of the Philistines.
Judges 13:5 (World English Bible)
Samson was never to cut his hair or drink wine. When Manoah asked the angel's name, he answered that it was wonderful, and then rose to heaven in the flame of the altar.
