What does the Bible say about partial obedience?

Partial obedience is addressed in Scripture primarily as a serious matter, demonstrating that God's commands are to be followed fully and without exception. For instance, the Israelites received specific directives regarding gathering manna in Exodus 16, and their failure to follow these in detail led to consequences. Similarly, King Saul's partial obedience in 1 Samuel 15, where he left some of the Amalekites alive, resulted in God rejecting him as king. These instances show that God expects His people to obey His commands completely, and anything less can lead to dire consequences.
