Should we keep the ‘law’? What is the handwriting of ordinances and are they same as the Ten Commandments?

To fully understand the Bible, we need to compare scripture with scripture to reach a holistic understanding - Is 28:10; 2 Tim 2:15. When the New Testament uses the word “law”, what is it referring to? I’ll start explaining this using Col 2:14-17. The main question is - What is the handwriting of ordinances and are they same as the Ten Commandments?
