The land bordering the coast is thickly covered for more than twenty stadia with an abundance of heavy trees of all sorts. (Xenophon, Anabasis 6.4.5:)

Who his own self bare our sins in his own body on the tree, that we, being dead to sins (King James version)

The God of our fathers raised up Jesus, whom ye slew and hanged on a tree. Acts 5:30 (King James Version)

 When Jesus died on that tree, he bore the awful curse of the law for us so that we might be saved. (1997, Warren W. Wiersbe, The Names of Jesus)

Oh, that's not to say Peter's life was easy. In fact, he, too, ended up on a tree—not hung up by guilt, but crucified upside down on a cross for the sake of the One who not only hung on a tree for him, but rose and lived within him, empowering him to live a life of incredible impact and ministry. (2004, Jon Courson, Jon Courson's Application Commentary, page 1130)

Jesus was crucified on a tree to give us life (2015, Bruce Thomas, God's Purpose for His Creation).

Outside of Jerusalem, at Golgotha, Jesus was crucified on a tree with two other thieves because He claimed to be the king of the Jews (2022, Sharmila Panirselvam, Life in the Hands of Jesus).
