How often it seems that problems come in multiples. Certainly Satan looks for any possible way to cause us to become discouraged and turn our backs on God feeling that He has let us down.
David was dealing with more than a plate full. Because Saul was seeking his life, he and his 600 men and their families had sought asylum in Philistine territory. What an awkward situation they found themselves in when the Philistines were going to war against Israel and they were expected to fight with the Philistines (see 1 Samuel 29)! It must have been God's intervention that caused the Philistine princes to reject their help and to send them back to their homes.
