Hanging on a Tree: A Word Study on ξύλον (Xylon) in Acts 5:30

Folks, just the other day I was reading Acts 5:30. The verse says the leaders murdered Jesus “by hanging on a tree.” I thought that Jesus died on a cross. And noticed something else that is true: Luke, who wrote both the Gospel and the book of Acts, only uses the word “tree” in Acts. He does not use it that way in the Gospel. That is not a problem. It is a beautiful little window into how the early church preached.

Let’s walk through it the way we do on Blue Letter Bible—slowly, looking at the words, the context, and where else Scripture speaks.

The Verse and the Setting

In Acts 5 the apostles have been arrested again. They are standing before the same council that condemned Jesus. Peter says:

“The God of our fathers raised up Jesus whom you murdered by hanging on a tree. Him God has exalted to His right hand to be Prince and Savior, to give repentance to Israel and forgiveness of sins.” (Acts 5:30-31, NKJV)

This is not a history lesson. It is a bold witness. Peter is telling the very men who pushed for the crucifixion that the One they put to death is now alive and exalted.

The Greek Word

The word translated “tree” is ξύλον (xylon or xulon), Strong’s G3586.

Blue Letter Bible lists the basic meaning this way: timber (as fuel or material); by implication a stick, club, or tree, or other wooden article or substance. The King James uses it for tree, staves, wood, and stocks.

Thayer’s lexicon is helpful here. It notes that xylon can mean wood in general, something made of wood, or a tree. In a few important places it is used for “a beam from which any one is suspended, a gibbet, a cross.” That is not the ordinary classical use of the word, but it is the way the New Testament writers use it when they are pointing back to the Old Testament.

You see it used in different ways in the New Testament:

• Clubs or staves in the hands of the men who arrested Jesus (Matthew 26:47, 55; Mark 14:43, 48; Luke 22:52).
• The stocks that held Paul’s feet in prison (Acts 16:24).
• Ordinary wood (1 Corinthians 3:12; Revelation 18:12).
• A living tree, including the tree of life (Luke 23:31; Revelation 2:7; 22:2, 14).
• And, in a cluster of verses, the instrument of Jesus’ death (Acts 5:30; 10:39; 13:29; Galatians 3:13; 1 Peter 2:24).

The ordinary word for the cross itself is σταυρός (stauros). That is the word Luke uses in the Gospel when he describes the actual event—Jesus carrying the cross, being crucified, and so on. When the apostles are preaching, especially to Jewish hearers, they often choose xylon. They are not confused about what happened. They are choosing a word that carries an Old Testament echo.

Why “Tree” in Acts and Not in the Gospel?

Luke is careful. In the Gospel he is writing the historical account of the crucifixion, so he uses the normal term for the Roman instrument of death. In Acts he is recording the words the apostles actually spoke. When they stood before Jewish audiences—the Sanhedrin, Cornelius and his household, the synagogue in Antioch—they deliberately said “tree.”

They were pointing back to Deuteronomy 21:22-23:

“If a man has committed a sin deserving of death, and he is put to death, and you hang him on a tree, his body shall not remain overnight on the tree, but you shall surely bury him that day… for he who is hanged is accursed of God.”

In the Septuagint (the Greek Old Testament the early church used), the word for that “tree” is the same xylon. Anyone hanged on a tree was under the curse of God. The religious leaders knew that. When they insisted Jesus be crucified, they were not only putting Him to death; they were hanging Him on a tree so that, in their view, He would be marked as cursed.

We know that Peter, Paul, and the others did not hide that. They brought it into the open. The very thing the leaders meant for shame, God used for our redemption.

The Light of the New Testament

Paul makes the connection explicit in Galatians 3:13:

“Christ has redeemed us from the curse of the law, having become a curse for us (for it is written, ‘Cursed is everyone who hangs on a tree’).”

The same idea appears in 1 Peter 2:24:

“Who Himself bore our sins in His own body on the tree, that we, having died to sins, might live for righteousness—by whose stripes you were healed.”

And again in Acts 10:39 and 13:29. Each time the writers use xylon, they are saying the same thing: Jesus took the place of the cursed one so that we might receive the blessing.

What It Means for Us

The cross was a real Roman instrument of execution. Jesus died there. But the apostles used the language of the tree because they wanted their hearers to see the deeper meaning. The curse that belonged to us fell on Him. He became a curse for us so that the blessing of Abraham might come to us through faith.

That is why the “tree” appears in the preaching of Acts and in the letters, while the Gospel narratives simply describe the cross. Luke in his accurate writings is faithful to both the historical fact and the words that were spoken. There is no contradiction. There is only the careful, Spirit-led proclamation of what God did at Calvary.

Folks, the One who was hanged on the tree is the same One God raised up and exalted to His right hand. He is Prince and Savior. He still gives repentance and forgiveness of sins. The tree that looked like defeat was the place where the curse was broken for everyone who believes.

Keep looking at the words. The more you stay in the Scriptures, the more these details open up and show you how thoroughly God has provided for us in Jesus. He took what was ours—the curse—and gave us what is His—life, blessing, and peace with God.

Keep studying and keep Bible-Strong.
