Proverbs 27:3 A stone is heavy, and the sand weighty; but a fool's wrath is heavier than them both. 4 Wrath is cruel, and anger is outrageous; but who is able to stand before envy?
[Patriarchs & Prophets pp 651] Desiring to be freed from the presence of his rival, the king “removed him from him, and made him his captain over a thousand.... But all Israel and Judah loved David.” The people were not slow to see that David was a competent person, and that the affairs entrusted to his hands were managed with wisdom and skill. The counsels of the young man were of a wise and discreet character, and proved to be safe to follow; while the judgment of Saul was at times unreliable, and his decisions were not wise.
Though Saul was ever on the alert for an opportunity to destroy David, he stood in fear of him, since it was evident that the Lord was with him. David's blameless character aroused the wrath of the king; he deemed that the very life and presence of David cast a reproach upon him, since by contrast it presented his own character to disadvantage. It was envy that made Saul miserable and put the humble subject of his throne in jeopardy. What untold mischief has this evil trait of character worked in our world!
The same enmity existed in the heart of Saul that stirred the heart of Cain against his brother Abel, because Abel's works were righteous, and God honored him, and his own works were evil, and the Lord could not bless him. Envy is the offspring of pride, and if it is entertained in the heart, it will lead to hatred, and eventually to revenge and murder. Satan displayed his own character in exciting the fury of Saul against him who had never done him harm.
John 8:44 The devil was a murderer from the beginning, and abode not in the truth, because there is no truth in him. When he speaketh a lie, he speaketh of his own: for he is a liar, and the father of it.
May God add His blessing to the study of His word. "Good night" and God bless!
