Yes, it is the ever popular, always-traditional, "If you disagree with me about what the Bible says, it doesn't matter because God is on my side!"
And Good Brother, if you can't find the sabbatical year and Jubilee year passages of the Torah Law, I've told you before: get yourself a Bible concordance OR simply learn to use the Google search engine. You always want me to do your Bible tutoring for you. I realize that these concepts are new to you but trust me: type "sabbath year" or "sabbatical year" or "Jubilee year" together with the word "Bible" into Google and you will have enough tutoring material to keep you off the streets for many many YOMs!
(And if you ever get to the point where you are open to learning about the Bible, research how both ancient and modern Hebrews define a 24hour day. No, it is not evening through morning. It runs from sunset to sunset!)
Tradition may be comforting to you. But eventually you should investigate what the Bible actually states in the Hebrew text. Even if you are afraid to venture into other Hebrew language literature of ancient times, the TANAKH itself (that is, the Old Testament in Hebrew) uses the word YOM for meanings besides 24-hour day.) Yes, shaking loose from tradition can be scarey---especially when you are likely to be shunned by your peers. But which is more important: peer acceptance or what God's Bible actually says?
