1 Samuel 16:14 - Wesley's Explanatory Notes

Departed — God took away that prudence, and courage, and alacrity, and other gifts wherewith be had qualified him for his public employment. From the Lord — That is, by God's permission, who delivered him up to be buffeted of Satan. Troubled — Stirred up in him unruly and tormenting passions; as envy, rage, fear, or despair. He grew fretful, and peevish, and discontented, timorous and suspicious, frequently starting and trembling.
