The verse emphasizes that prosperity isn't just about outward actions but about the constant, internal digestion of God's Word, so much so that it shapes what we speak and how we think day and night. This deep, lived understanding is what leads to genuine success, not merely following rules.
This Book of the Law shall not depart from your mouth, but you shall meditate on it day and night, so that you may be careful to do according to all that is written in it. For then you will make your way prosperous, and then you will have good success.
