If eating from the tree of good and evil brought death, what was the punishment for Adam and Eve? We know that they went on to have children, so death does not seem to have doomed them immediately. And nowhere does Scripture indicate that God forgave this disobedient pair. Was their punishment that they would die in a shortened period of time?

Adam lived to the age of 930, so a shortened life doesn’t seem to be the right answer. Actually, I’m not sure if you’re asking about the text itself or about the interpretive tradition (they’re quite different!). If the former, the text says they were punished by being kicked out of that comfortable garden: Adam was condemned henceforth to work for his food, and Eve to give birth in pain. So both were punished, but apparently not with death. On the other hand, the Bible’s earliest interpreters did indeed believe their punishment to be mortality, that is, an end to the immortal life that was one of the perks of living in the Garden.
