1 sn Jesus was stressing that all stand at risk of death, if they do not repent and receive life.
2 tn Or “you will all likewise perish,” but this could be misunderstood to mean that they would perish by the same means as the Galileans. Jesus’ point is that apart from repentance all will perish.
3 sn He is not God of the dead but of the living. Jesus’ point was that if God could identify himself as God of the three old patriarchs, then they must still be alive when God spoke to Moses; and so they must be raised.
4 tn On this syntax, see BDF §192. The point is that all live “to” God or “before” God.
