So the Talmud is not the Bible though. The Bible, the Old Testament and what the Jews consider Holy Text is the Torah. The Talmud is a body of works of various rabbis; the Talmud mostly the two books of Gemarah and the Mishnah and should not carry the same weight as the Torah. So if one were to consider the Bible (Torah) only, the legal age of an adult appears to be 20. What the Jews did or made up on their own afterwards would be of their own tradition and in some cases in contradiction to the Bible. The Bible - and Jewish tradition many times do not line up. Even in New Testament times there were issues with this - as Jesus had a beef with the Pharisees because they had all these other laws and rules one had to obey that were not part of the Torah.
