1 Samuel 19, Psalm 23, Psalm 59

1. Saul Tries to Kill David
In this passage, Saul orders Jonathan and his attendants to kill David.  Jonathan warns David of Saul's plot against him, though.  Jonathan then goes to Saul and persuades him to spare David's life by reminding him of how Israel benefited from David's great victory over Goliath.  At this point it appears that Saul has cast off his evil thoughts regarding David.  Later, though, an evil spirit from the Lord comes upon Saul, and he attempts to kill David while he plays the harp in his house.  David escapes from Saul's house, and Saul sends men to surround his house.  Michal persuades David to flee that evening, and she places an idol in his bed to deceive Saul's men when they come to capture him.  Saul uncovers her deception and pursues David to Naioth at Ramah - yet the Spirit of the Lord comes upon him and his men, causing them to prophesy.

I wonder why Michal and David had an idol in their house.  Was the Lord displeased with them?  Was a particular Hebrew phrase incorrectly translated as "idol" in this case?  I hope to meet Michal and David someday and learn more about this...
 
2. Psalm 23
In this passage, David portrays himself as a lamb being led by his shepherd, the Lord.  He describes the comfort that he experiences as the Lord leads him through life-threatening situations.  He also describes the triumphs that the Lord brings him, and he expresses his confidence that the Lord will never leave him.

I wonder if David wrote this classic psalm after Jonathan informed him of Saul's plot against him.  If so, could Saul have been one of David's "enemies" in verse 5?

3. Psalm 59
In this passage, David prays that the Lord would deliver him from his enemies.  He states that he has done no wrong; thus, he prays that the Lord would rescue him from his enemies.  He portrays his enemies as a pack of snarling dogs, and he expresses his confidence that the Lord will enable him to defeat them.  Now he prays that the Lord would defeat his enemies without destroying them - so that they would be a testimony to the Lord's sovereignty and power.

While I have not studied the Psalms in depth, my impression is that many of them involve David praying that the Lord would deliver him from his enemies.
