1st Samuel 18:4 And David behaved himself wisely in all his ways; and the Lord was with him. 15 Wherefore when Saul saw that he behaved himself very wisely, he was afraid of him.
[Patriarchs & Prophets pp 651>652] 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.
The king kept a strict watch upon David, hoping to find some occasion of indiscretion or rashness that might serve as an excuse to bring him into disgrace. He felt that he could not be satisfied until he could take the young man's life and still be justified before the nation for his evil act. He laid a snare for the feet of David, urging him to conduct the war against the Philistines with still greater vigor, and promising, as a reward of his valor, an alliance with the eldest daughter of the royal house.
1st Samuel 18:17 And Saul said to David, Behold my elder daughter Merab, her will I give thee to wife: only be thou valiant for me, and fight the Lord's battles. For Saul said, Let not mine hand be upon him, but let the hand of the Philistines be upon him.
May The Lord add His blessing to the study of His word. God bless!
