Judges 13:1 says, And the children of Israel did evil again in the sight of the LORD; and the LORD delivered them into the hand of the Philistines forty years.  The cycle repeats once more.  After a period of peace, the people of God do evil in His sight.  It mat be that periods of peace and prosperity are more dangerous to us spiritually than periods of war and suffering.  In times when things are really bad, we tend to look to God for help, but when life is going along smoothly, it seems that we sometimes forget our need for Him to guide us.  Once more, God allowed them to be defeated, this time by the Philistines.  Verse two states, And there was a certain man of Zorah, of the family of the Danites, whose name was Manoah; and his wife was barren, and bare not.  We are told of a certain man named Manoah whose wife was barren.  Manoah was of the tribe of Dan, who was born to one of the handmaidens of Jacob.  Still, Jacob had said that Dan would judge his people.  The descendants of Dan, and the children of the other handmaidens were just as much a part of the children of Israel as were those born to Jacob's wives.  Verse three adds, And the angel of the LORD appeared unto the woman, and said unto her, Behold now, thou art barren, and bearest not: but thou shalt conceive, and bear a son.  An angel of God appeared to Manoah's wife and told her that even though she had been barren that she was going to bear a son.  This had to be exciting news to her.  Verse four continues, Now therefore beware, I pray thee, and drink not wine nor strong drink, and eat not any unclean thing:  The angel then gave Manoah's wife some prenatal care instructions we might say.  She was to drink no wine or strong drink or eat any unclean thing.  This had not only to do with physical health, but it also had to do with spiritual health.  If we are follower of Christ, we are to do our best to keep things that are spiritually unclean from coming into our lives, and I also believe that we are to do our best to maintain a physically healthy lifestyle.  Verse five concludes, For, lo, thou shalt conceive, and bear a son; and no rasor shall come on his head: for the child shall be a Nazarite unto God from the womb: and he shall begin to deliver Israel out of the hand of the Philistines.  The angel also told the woman that after her son was born that his hair was never to be cut, because he was to be a Nazarite unto God and that he would begin to deliver his people from the Philistines.  This was all promised by God even before the child was born.  God has a plan for our lives even before we are born, whether we ever look to Him to show us what that purpose is or not.   Of course, in order to fulfill that purpose, we must first accept Jesus Christ as our Savior and Lord.  Verse six declares,Then the woman came and told her husband, saying, A man of God came unto me, and his countenance was like the countenance of an angel of God, very terrible: but I asked him not whence he was, neither told he me his name:  Manoah's wife came to him and told him that she had met a man of God who looked like an angel of God, very terrible.  We don't normally think of angels appearing terrible, but I believe that his appearance was such as to strike awe into the woman, and in that sense it was terrible to her.  She also said that the angel did not tell her his name.  If an angel were to appear to someone today, his name would not be important, but his message would.  Verse seven adds, But he said unto me, Behold, thou shalt conceive, and bear a son; and now drink no wine nor strong drink, neither eat any unclean thing: for the child shall be a Nazarite to God from the womb to the day of his death.  Manoah's wife told him what the angel had told her.  She was to bear a son, and he would be raised as a Nazarite from birth.  It would be nice if we knew from birth what we were to do in life, but we don't get that clear calling from birth.  Verse eight declares, Then Manoah intreated the LORD, and said, O my Lord, let the man of God which thou didst send come again unto us, and teach us what we shall do unto the child that shall be born.  Manoah asked God to send the angel again to teach them how to raise the child.  Even if we know what God wants us to do, we must rely on Him to teach us and empower us to do it to the best of our ability.  We do not really need an angel to come to us and teach us though since as believers in Christ we have the Holy Spirit indwelling us to guide and empower us.
