What does Judges 13:8 mean?
Manoah (Judges 13:2) could have responded in several ways to his wife's story. She claimed a man who looked like an angel told her she would have a son, despite being barren (Judges 13:3–5). Even more unique was her claim that this child is to be set apart under Nazirite vows (Numbers 6:1–20)—no contact with alcohol, grapes, or cutting his hair—and that was destined to begin to save Israel from Philistine oppression (Judges 13:1).Manoah responds in faith and a measure of anxiety. He believes his wife and trusts this message (Judges 13:6–7) was from God. He immediately prays to the Lord to send the man of God back to teach them how to raise this child. Some commentators suggest Manoah doubts his wife's story and wants to see it confirmed with his own eyes. According to what he says, however, Manoah is asking for details about "how" to obey the command, not verifying "if" it was given. That's a prayer of deep faith.
Judges 13:8–25 explains how Manoah learned of his wife's interaction with a messenger from God. He prays for more understanding, so he can properly fulfill his obligations. The angel of the Lord appears, again, and repeats his instructions. The child is to be consecrated as a Nazirite for his entire life. Manoah prepares a sacrifice, and the angel disappears into the flames. This further confirms the truth of the message. Manoah and his wife name their child Samson, who shows signs of blessing and the influence of God's Spirit from an early age.
The Lord appoints another deliverer for Israel, this time in response to oppression under the Philistines. An impressive stranger appears to Manoah and his wife, announcing they will have a son. This child is to be set apart as a Nazarite from before birth until death. His mother must not drink wine or strong drink or eat any unclean thing. This visitor then disappears into the flames of a burnt offering. The couple realizes they have seen a manifestation of Yahweh, Himself. Samson is born and soon shows signs of God's influence.
