1st Samuel 19:20 And Saul sent messengers to take David: and when they saw the company of the prophets prophesying, and Samuel standing as appointed over them, the Spirit of God was upon the messengers of Saul, and they also prophesied.
[Patriarchs & Prophets pp 653>654] Precious were the lessons that David learned from the teacher of Israel. David believed that the troops of Saul would not be ordered to invade this sacred place, but no place seemed to be sacred to the darkened mind of the desperate king. David's connection with Samuel aroused the jealousy of the king, lest he who was revered as a prophet of God throughout all Israel should lend his influence to the advancement of Saul's rival. When the king learned where David was, he sent officers to bring him to Gibeah, where he intended to carry out his murderous design.
The messengers went on their way, intent upon taking David's life; but One greater than Saul controlled them. They were met by unseen angels, as was Balaam when he was on his way to curse Israel. They began to utter prophetic sayings of what would occur in the future, and proclaimed the glory and majesty of Jehovah. Thus God overruled the wrath of man and manifested His power to restrain evil, while He walled in His servant by a guard of angels. The tidings reached Saul as he eagerly waited to have David in his power; but instead of feeling the rebuke of God, he was still more exasperated, and sent other messengers.
These also were overpowered by the Spirit of God, and united with the first in prophesying. The third embassage was sent by the king; but when they came into the company of the prophets, the divine influence fell upon them also, and they prophesied. Saul then decided that he himself would go, for his fierce enmity had become uncontrollable. He was determined to wait for no further chance to kill David; as soon as he should come within reach of him, he intended with his own hand to slay him, whatever might be the consequences.
1st Samuel 19:22 Then went he also to Ramah, and came to a great well that is in Sechu: and he asked and said, Where are Samuel and David? And one said, Behold, they be at Naioth in Ramah. 23 And he went thither to Naioth in Ramah: and the Spirit of God was upon him also, and he went on, and prophesied, until he came to Naioth in Ramah.
May The Lord add His blessing to the study of His word. God bless!
