The concept of cursing and blessing in association with a tree is found in the larger narrative of Scripture. In Genesis 3 Eve and then Adam eat fruit from a tree from which they were forbidden to eat. In Revelation 22:14 the eternal state includes those who eat from the tree of life. A tree was involved in the entry of sin into humanity (through the tree in the Garden), the answer to sin for humanity (through the cross), and the ultimate removal of sin in eternity (through the tree of life).
Under the Mosaic Law, those who were hanged on a tree were cursed. The law made it illegal to leave the body hanging overnight. This law applied to Jesus, who was executed on a tree, although He had done no wrong. Jesus’ dead body was removed from the cross on the same day of His death and was buried. Jesus took the curse of sin upon Himself to redeem us from sin.Then 3 days later he beat Death, Hell and the Grave by walking out.
