You know how atheists never venture outside of the Old Testament lest they run into teachings of Jesus that convict them of wrong? And you know how atheists accuse Christians of cherry-picking verses to make our case? Do you think atheists ever do the same thing? Like, have you ever seen them ranting about this?
“The king must not acquire great numbers of horses for himself or make the people return to Egypt to get more of them. He must not take many wives, or his heart will be led astray. He must not accumulate large amounts of silver and gold.”
Immense riches are seldom possessed by leaders of countries or corporations without the oppression of their citizens, employees or investors. Unlike their neighbours, unlike our modern industrial societies, people in ancient Israel (those who atheists call bronze-age goat herders) were to make sure they did nothing to take advantage of each other.
Peace, Mercy and Justice were then and are today to be the hallmark of God's people.
