The expression "spy out the land" means to investigate or explore a new or unknown territory before making a decision or taking action. It comes from the story in the Bible when Moses sent spies to scout the land of Canaan before taking the Israelites there. In modern times, the expression is used to describe conducting research or gathering information before starting a project or taking a risk. For example, if you are considering moving to a new city, you might "spy out the land" by researching the housing market, job opportunities, and quality of life in that area before making a final decision.
