I mean, there's not really any particular technique to it, you just read it with a very critical eye. Skip all the boring shit like who begets who and whatever the fuck, you can even start with the New Testament if you like, though I think reading Genesis and Exodus at the very least is worth it since they're pretty good. You can look up the historical context for each book to get more more insight into why/when they were written and the material conditions that gave birth to them. The Bible is like 50/50 between some of the most life-affirming and genuinely great writings you can come across, and some of the worst, most disgusting, most reactionary things you'd have the displeasure of reading, but ultimately I still think it's worth giving it a try, if only because it's such an important document that is central to so much of culture and history. Look into Liberation Theology afterwards and own conservative Christians with the true word of our Lord and Savior and based proto-communist Jesus Christ :jesus-cleanse:
