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.
Samson was to live as a Nazirite because God would "begin" to deliver Israel from the Philistines through him (Judges 13:5). Samuel and David would complete this task (1 Samuel 7:10-14; 2 Samuel 5:17-25). Samson proved unfaithful in his separation to God. John the Baptist, who was apparently another Nazirite from birth, was faithful. He shows us what Samson could have become if he had valued his opportunity to serve God and had preserved his dedication to God. Evidently Manoah’s wife assumed that the Angel was a prophet (Judges 13:6).
