Cursed on a Tree

Deuteronomy 21:10–23

This passage covers several laws that feel far from us, but it ends with a line the New Testament seizes on to explain the cross.

The chapter begins with a striking mercy. If an Israelite soldier wanted to marry a woman captured in war, he couldn’t simply take her. She was given a full month to mourn her father and mother, to grieve everything she’d lost (Deut 21:12-13). Only then could she become his wife, with the full status of a wife. And if he later wanted to divorce her, he couldn’t sell her or treat her as property: “You must not sell her or treat her as a slave, since you have dishonored her” (Deut 21:14).

In the ancient world, captured women were routinely treated as spoils, objects, property to be used. God’s law cut against that completely. Even a captive woman had dignity. She got time to grieve. She got the protections of a wife, not the treatment of a possession. This was a radical elevation of a vulnerable person’s humanity in a brutal age. God saw her as a person, not plunder.

Next comes a law about inheritance. A man with two wives couldn’t play favorites with their sons, giving the firstborn’s double portion to the son of the wife he preferred (Deut 21:15-17). The rightful firstborn got his due regardless of the father’s affections. Fairness overruled favoritism, protecting the son who might otherwise be cheated by a father’s bias.

Then the hard one: the rebellious son. A persistently, incorrigibly rebellious son, one who was a drunkard and a glutton and would not respond to any discipline, could be brought by his parents before the elders and be subject to the severest penalty (Deut 21:18-21). This is jarring to us, and it should be. But notice the safeguards: it required both parents to agree, a public hearing before the elders, and a pattern of hardened rebellion, not a single act. There’s no record in Scripture of this penalty ever being carried out. The law seems designed more to underscore the gravity of honoring parents and the danger of unchecked rebellion than to be regularly enforced. Rebellion against parents, in Israel’s structure, was a threat to the whole covenant community.

And then the verse that echoes through the New Testament. “If someone guilty of a capital offense is put to death and their body is exposed on a pole, you must not leave the body hanging on the pole overnight. Be sure to bury it that same day, because anyone who is hung on a pole is under God’s curse” (Deut 21:22-23).

A person executed and hung on a tree was under God’s curse. The exposed body was a public sign of divine judgment. And it had to be taken down and buried the same day, so the land wouldn’t be defiled.

Paul saw the cross in this verse, and it changed everything. “Christ redeemed us from the curse of the law by becoming a curse for us, for it is written: ‘Cursed is everyone who is hung on a pole’” (Gal 3:13). Jesus was crucified, hung on a tree, and by this ancient law, that meant he bore the curse. But it wasn’t his own curse. He had no sin. He took ours.

That’s the staggering exchange at the heart of the gospel. The curse we earned by breaking God’s law fell on Jesus instead. He hung on the tree, under the curse, so we could go free. And they took his body down and buried it that same day, exactly as the law required.

The curse was real.

Jesus took it on the tree.

For you.
