'Law of Moses' in the Bible

And when the time for their purification came [that is, the mother’s purification and the baby’s dedication] according to the Law of Moses, they brought Him up to Jerusalem to present Him to the Lord [set apart as the Firstborn]

Then He said to them, “This is what I told you while I was still with you, everything which has been written about Me in the Law of Moses and the [writings of the] Prophets and the Psalms must be fulfilled.”
