For JW's, we read the Bible in increments ( a couple of chapters) every week as part of our personal study and prep for our midweek meeting....and then we share whatever research we have personally had time for with our congregation members (over Zoom these days.)
We start at Genesis and when we get to Revelation, we start back in Genesis again. Doing research is always fun for me. If I find something that's difficult, I do a bit of digging to help me make sense of difficult passages. We have an extensive library to help us with our research, but we are free to glean more information from other scholarly sources. I particularly like Strongs Concordance for help with the meanings of original language words.
Some parts of the Hebrew scripture are laborious to read but, its usually very detailed descriptions of things pertaining to the design and decoration of the Tabernacle or the Temple.
We have just finished Exodus and starting Leviticus next week.
My very favorite book is Genesis, followed the prophetic books in the Hebrew scriptures, and I love the gospels as well. Revelation is deep, but not beyond our understanding.
We are starting a new study in Ezekiel in a couple of weeks. I am really looking forward to that. The deep prophetic books need full concentration and a generous helping of God's spirit.
