'Trees' in the Bible

And afterwards Joshua smote them, and put them to death, and hanged them on five trees; and they were hanging upon the trees until the evening.

And it came to pass at the time of the going down of the sun, that Joshua commanded, and they took them down off the trees, and cast them into the cave where they had been hid, and laid great stones before the cave's mouth, which remain to this very day.
