Before Samson was born, Israel turned from God so he allowed them to be at odds with the Philistines. But, God had plans to redeem His people and save them from the tyranny of the Philistines. Through Samson, they would begin to be free of the Philistines. Jesus would come as The Angel of the Lord to speak to Samson’s parents to let them know that they would have a child to be used by God and He gave them instructions on how to raise him.
Judges 13:1-25
Again the children of Israel did evil in the sight of the LORD, and the LORD delivered them into the hand of the Philistines for forty years. Now there was a certain man from Zorah, of the family of the Danites, whose name was Manoah; and his wife was barren and had no children. And the Angel of the LORD appeared to the woman and said to her, “Indeed now, you are barren and have borne no children, but you shall conceive and bear a son. Now therefore, please be careful not to drink wine or similar drink, and not to eat anything unclean. For behold, you shall conceive and bear a son. And no razor shall come upon his head, for the child shall be a Nazirite to God from the womb; and he shall begin to deliver Israel out of the hand of the Philistines.” So the woman came and told her husband, saying, “A Man of God came to me, and His countenance was like the countenance of the Angel of God, very awesome; but I did not ask Him where He was from, and He did not tell me His name. And He said to me, ‘Behold, you shall conceive and bear a son. Now drink no wine or similar drink, nor eat anything unclean, for the child shall be a Nazirite to God from the womb to the day of his death.’ ” Then Manoah prayed to the LORD, and said, “O my Lord, please let the Man of God whom You sent come to us again and teach us what we shall do for the child who will be born.” And God listened to the voice of Manoah, and the Angel of God came to the woman again as she was sitting in the field; but Manoah her husband was not with her. Then the woman ran in haste and told her husband, and said to him, “Look, the Man who came to me the other day has just now appeared to me!” So Manoah arose and followed his wife. When he came to the Man, he said to Him, “Are You the Man who spoke to this woman?” And He said, “I am.” Manoah said, “Now let Your words come to pass! What will be the boy’s rule of life, and his work?” So the Angel of the LORD said to Manoah, “Of all that I said to the woman let her be careful. She may not eat anything that comes from the vine, nor may she drink wine or similar drink, nor eat anything unclean. All that I commanded her let her observe.” Then Manoah said to the Angel of the LORD, “Please let us detain You, and we will prepare a young goat for You.” And the Angel of the LORD said to Manoah, “Though you detain Me, I will not eat your food. But if you offer a burnt offering, you must offer it to the LORD.” (For Manoah did not know He was the Angel of the LORD.) Then Manoah said to the Angel of the LORD, “What is Your name, that when Your words come to pass we may honor You?” And the Angel of the LORD said to him, “Why do you ask My name, seeing it is wonderful?” So Manoah took the young goat with the grain offering, and offered it upon the rock to the LORD. And He did a wondrous thing while Manoah and his wife looked on— it happened as the flame went up toward heaven from the altar—the Angel of the LORD ascended in the flame of the altar! When Manoah and his wife saw this, they fell on their faces to the ground. When the Angel of the LORD appeared no more to Manoah and his wife, then Manoah knew that He was the Angel of the LORD. And Manoah said to his wife, “We shall surely die, because we have seen God!” But his wife said to him, “If the LORD had desired to kill us, He would not have accepted a burnt offering and a grain offering from our hands, nor would He have shown us all these things, nor would He have told us such things as these at this time.” So the woman bore a son and called his name Samson; and the child grew, and the LORD blessed him. And the Spirit of the LORD began to move upon him at Mahaneh Dan between Zorah and Eshtaol.
How do we know this was Jesus that appeared to them? No one knows for sure but some of the clues I have noticed was first that He accepted their offering. An angel of God would not accept any form of worship as the angel speaking with John would attest.
Revelation 19:9-10
Then he said to me, “Write: ‘Blessed are those who are called to the marriage supper of the Lamb!’ ” And he said to me, “These are the true sayings of God.” And I fell at his feet to worship him. But he said to me, “See that you do not do that! I am your fellow servant, and of your brethren who have the testimony of Jesus. Worship God! For the testimony of Jesus is the spirit of prophecy.”
I think The Angel of the Lord was also making a point when He said that you must offer an offering only to God. I think He was making a point that it was God that he was speaking to. Jesus did the same to one of the Teachers of the Law during His ministry.
Matthew 19:16-17
Now behold, one came and said to Him, “Good Teacher, what good thing shall I do that I may have eternal life?” So He said to him, “Why do you call Me good? No one is good but One, that is, God. But if you want to enter into life, keep the commandments.”
When Manoa asks His name, He does not tell him, only that it is “wonderful.”
Revelation 19:11-13
Now I saw heaven opened, and behold, a white horse. And He who sat on him was called Faithful and True, and in righteousness He judges and makes war. His eyes were like a flame of fire, and on His head were many crowns. He had a name written that no one knew except Himself. He was clothed with a robe dipped in blood, and His name is called The Word of God.
Isaiah 9:6-7
For unto us a Child is born, Unto us a Son is given; And the government will be upon His shoulder. And His name will be called Wonderful, Counselor, Mighty God, Everlasting Father, Prince of Peace. Of the increase of His government and peace There will be no end, Upon the throne of David and over His kingdom, to order it and establish it with judgment and justice from that time forward, even forever. The zeal of the Lord of hosts will perform this.
It is interesting that Manoa realized he was in the presence of God when He ascended to heaven. He was fearful that he would die because He saw God, but with Jesus, we can look upon God. Jesus came to this earth so that we would no longer be separated from God, that we can look upon Him and have direct access to the Father, to save us and redeem us from our sins. His wife was wise and reminded him that God had a purpose for them.
Acts 1:9-11
Now when He had spoken these things, while they watched, He was taken up, and a cloud received Him out of their sight. And while they looked steadfastly toward heaven as He went up, behold, two men stood by them in white apparel, who also said, “Men of Galilee, why do you stand gazing up into heaven? This same Jesus, who was taken up from you into heaven, will so come in like manner as you saw Him go into heaven.”
Isaiah 6:1-7
In the year that King Uzziah died, I saw the Lord sitting on a throne, high and lifted up, and the train of His robe filled the temple. Above it stood seraphim; each one had six wings: with two he covered his face, with two he covered his feet, and with two he flew. And one cried to another and said: “Holy, holy, holy is the LORD of hosts; The whole earth is full of His glory!” And the posts of the door were shaken by the voice of him who cried out, and the house was filled with smoke. So I said: “Woe is me, for I am undone! Because I am a man of unclean lips, and I dwell in the midst of a people of unclean lips; for my eyes have seen the King, The LORD of hosts.” Then one of the seraphim flew to me, having in his hand a live coal which he had taken with the tongs from the altar. And he touched my mouth with it, and said: “Behold, this has touched your lips; your iniquity is taken away, and your sin purged.”
This also describes the parallels of Jesus in this story. He is the ultimate redeemer and savior of His people, not only the Israelites, but all who call on His name. He came to save us from our sins so that we can live in eternity with Him.
John 3:17
For God did not send His Son into the world to condemn the world, but that the world through Him might be saved.
