1. Back in the day no one ever used to give chapter and verse. That shyt wasn't even invented until way later. Those who know know. But if you really want, check out Leviticus 25:10-23, Isaiah 5:8-10, and Micah 2. Then look at what Jesus's crew did in Acts 2 and Acts 4, and read some of the early Church commentary on this shyt like what St. Basil the Great wrote out when his people were facing disastrous times (his homily "In Times of Famine and Drought" is the most relevant but I only have the hardcopy right now, don't see the full text online). Here's some similar sentiments though:
St. Basil’s Sermon to the Rich
2. Those verses are without any doubt a response to the edict in Leviticus 25, which insisted that God owns the land, not man, and that every family has a right to its own place in that land.
3. God has no problem with those who are successful with what they have, such that they use their success for the benefit of others. What God has a problem with is those who take advantage of their success to then gain more at the expense of those who have less. That's why all debts were cancelled every 7 years. That's why you're not supposed to accumulate property at the expense of your countryman's property ownership. That's why exploiting workers, exploiting the poor, and earning blood money is explicitly outlawed. That's why the Bible is so firmly against charging interest to the poor or to fellow believers - you're not supposed to make money by exploiting your brothers.
Jesus made clear, over and over, that the rich of his day were in flagrant violation of these principles, that they were taking advantage of their fellows, and that to follow him they had to divest themselves of their wealth. Do you think the rich have become more ethical and moral today? Do you think people are unexploited?
