1 Samuel 13:13-14 Saul stole Samuel's work:
Samuel said to Saul…"But now your kingdom shall not endure. The LORD has sought out for Himself a man after His own heart, and the LORD has appointed him as ruler over His people, because you have not kept what the LORD commanded you."
1 Samuel 15:28-29 Saul failed to do his own work:
So Samuel said to him, "The LORD has torn the kingdom of Israel from you today and has given it to your neighbor, who is better than you. "Also the Glory of Israel will not lie or change His mind; for He is not a man that He should change His mind."
1 Samuel 15:33 Samuel had to finish Saul's unfinished work:
And Samuel hewed Agag to pieces before the LORD at Gilgal.
For me to live is Christ.
