1 Samuel 30:6

And David was greatly distressed, deeply oppressed and anxious in spirit; for the people spake of stoning him, evidently putting all the blame upon him for joining Achish on his campaign against Israel, because the soul of all the people was grieved, full of bitterness, which has a tendency to be unreasonable, every man for his sons and for his daughters. But David encouraged himself in the Lord, his God, seeking strength and comfort in prayer and in firm confidence in the Lord, also by a direct inquiry of the Lord.
