"Blessed is the man who does not walk in the counsel of the wicked, nor stand in the way of sinners, nor sit in the seat of scoffers. But his delight is in the law of the Lord, and on his law he meditates day and night." (Psalm 1:1-2). This verse speaks of seeking good and delighting in the law of the Lord. King David of Israel was such a person, who sought the welfare of Israel by establishing 24 priestly divisions and 24 Levite divisions. He sought the mercy of God to rest upon him in order to bless Israel. This is where he found blessing, as it says, "Blessed is the man." (Psalm 1:1)On the other hand, "But those who seek to harm me will be destroyed; they will go down to the depths of the earth." (Psalm 63:9) This refers to Doeg and Ahithophel who sought to harm King David.
