Answer:
Saul disobeyed Samuel's instructions in several ways:
1. Offering sacrifices without waiting for Samuel: In one instance, Samuel instructed Saul to wait for him to arrive in Gilgal and offer sacrifices to God. However, Saul grew impatient and offered the sacrifices himself before Samuel's arrival. This act disregarded Samuel's authority and violated the specific instructions given to him.
2. Failing to completely destroy the Amalekites: God commanded Saul to completely destroy the Amalekite nation, including men, women, children, and animals. However, Saul spared King Agag and the best of the livestock, going against God's explicit instructions. Samuel confronted Saul for this disobedience, as sparing the Amalekites went against God's will.
3. Building a monument for himself: After a victory against the Amalekites, Saul built a monument in his own honor. This action showed a lack of humility and a desire for personal glory, which was contrary to the principles of kingship and submission to God's authority.
Overall, Saul's disobedience to Samuel's instructions included taking matters into his own hands by offering sacrifices, failing to carry out God's command to completely destroy the Amalekites, and seeking personal glory through the construction of a monument. These actions revealed Saul's disregard for God's authority and his failure to fulfill his responsibilities as king.
