Rebecca’s Womb & the Rivers of Babylon

Here’s a question that my Sunday school teacher couldn’t answer. Why did God promise the Israelites this particular land? Of all the uninhabited spots on the planet at that time, why would an all-knowing God promise His chosen people a piece of land that other people already inhabited? That’s why I never became a preacher like my parents. Based on my humanitarian outlook, I couldn’t logically justify the teachings.
