Tent of David
King David is known for many things, but less so as a unifier. He was the one who really united Israel and Judah, although this had already begun during the life of King Saul. However, this unity did not last long, at the beginning of King Rehoboam's reign, Israel separated from Judah. This is David's fallen booth. The fulfillment of the prophecy about the restoration of the fallen booth began in the life of the apostles.
You Shall Not Covet
Most Christians live their lives in the belief that, having been forgiven by God, they do not have to reap the consequences of their sins. However, they have to reap, which is why they stand bewildered when various disasters strike their lives, even though they pray, believe and trust.
