You can just note and read the verse quotes and scripture cites relative to their meaning given here and/or follow the other cites to Church Fathers and look up their verse quotes, scripture cites and continue on.
When you have finished with these interpretations, I can send you St. John Damascene's compilation as well as many encyclicals with their cites, verses and how these are interpreted in the Church.
Just let me know when you're ready for the next link, I'll wait.
If you're not truly interested in the Church's interpretation of Holy Scripture, then say so and I won't wait.
That is not a commentary.. showing the text in context ... giving the historic, language, and participants etc... what the RCC catechism does is cherry pick scripture out of context..not to expound the scripture but to support their doctrine.. because to the RCC scripture is secondary to their doctrine an traditions..so scripture is twisted and turned to ‘fit” where possible..
