Chs. 40-48 are pirkei hamikdash - the chapters devoted to Yechezkel's vision of a newly rebuilt temple. These are difficult chapters to learn - indeed the Rambam and Rashi struggled with them - but thankfully we have a hand to help. Rabbi Gamliel Shmalo introduces these chapters with a special focus on ch.42 and considers the idea of harmony - both in music and in religious architecture - as a lens through which to consider these chapters. https://www.sefaria.org/Ezekiel.42
