One link between this psalm and the previous one is the enjoyment of sleep even in demanding situations (3:5 and 4:8). In verse 1 of this psalm, David speaks to God, in verses 2-5 he speaks to powerful men opposing him, and in verses 6-8 he speaks to God again. The divisions in the outline of the psalm show how such enjoyment comes. It is always best to follow this order when speaking – first to God about the matter, second to men about the matter, and third to God again about the matter.
The title of the psalm is the first that mentions the chief musician, the individual who oversaw the public and communal praise offered to God. Not every psalm has this instruction in its heading, and while the reason for that inclusion or omission is not clear, yet what is clear is that this psalm was suitable for public expression of worship.
In verse 1, David prays about his unpleasant circumstances caused by opposition of ungodly men. Some commentators suggest the circumstances are the same as those behind Psalm 3 while others suggest Psalm 4 refers to a different time in David’s life.
What makes David confident as he prays? He gives three reasons, and all believers can and should use them.
First, David has a personal relationship with the Lord, a relationship marked by righteousness, a unique title of God (God of my righteousness) used only here in the Bible. David could have in mind his own God-produced righteous obedience to the Lord’s requirements, or to the righteousness of David’s God-given position as a divinely chosen king, or to the righteousness of Jesus given to believers by God as their standing in his presence (a standing David rejoiced in, as we can see from other psalms). Each way shows that the Lord loves righteousness, and mentioning it is always appropriate when praising of God.
Second, the Lord had heard and answered earlier prayers by David for divine help, and reference to such personal experience is a wise choice for believers to make when praying again about themselves. Perhaps that is why this psalm comes right after Psalm 3, since the earlier psalm describes a great divine deliverance that David experienced from the rebellion of Absalom.
Third, David knew that the Lord acted graciously when answering prayers of his people, a reminder that even the prayers of devout believers are not answered because they have some degree of merit with God because of their dedication. It is remarkable that David can appeal to God’s righteousness and God’s grace simultaneously.
In verses 2-5, David addresses his powerful opponents. Did he address them in his mind only? The verses do not hint that he used his words in that way. He was king, so his words could have been a royal announcement, and I would say that they were. His announcement is different from what we usually hear from rulers. In his words, David reveals the desires of his heart, the desires of a godly ruler chosen by God.
The opposition had focussed on David as ruler of Israel. His glory and status belonged to the position God had given him and which they now opposed (v. 2). Their discussions and announcements concerned his removal from his position, but that would not occur because the Lord had placed him there. The word for godly in verse 3 is singular and could refer to David himself as the one set apart by God as his chosen king. Moreover, David knew that the Lord listened to his prayers for deliverance from his opponents.
David’s counsel to his opponents was that they should be careful and self-controlled. He knew that they may have had cause for anger, but in their anger, they had to be careful not to sin. There is a short distance between anger and wrong actions. A better response than immediate fury is contemplation about the situation. Such contemplation brings the right perspective and gives calmness and rest of mind because it brings thoughts of God into the situation (v. 4).
In addition, such personal concern will bring desire for participation in divine worship. Without such preparation, participation in worship can turn into a sham. David knew that there was hope for his opponents provided they took the Lord’s will about himself as the chosen king into account (v. 5). They then could trust in their covenant God and doing so would prevent rebellion against his chosen king.
In verses 6-8 David resumes speaking to the Lord. He mentions that some of his supporters had a negative view of divine providence. The troubles that David prayed about had caused them to doubt the Lord’s care of them. It is often the case that believers can bring negatives assessments into the thoughts of other believers. David knew that the answer for their dilemma was repeated fulfilment by the Lord of the Aaronic blessing pronouncing divine favour.
His personal experience of the Lord’s joy at that time of trouble was greater than the happiest occasions of earthly joy known at harvest time. The joy he had was a personal gift from his God, and since he received it during a challenging time we can see once again that the joy of the Lord is our strength. David’s experience is a reminder that we can know the Lord’s joy and peace in such times.
It is not difficult to see how the experience of a godly earthly king would have a greater fulfilment in the experience of the sinless King when he found himself in difficulties from those opposed to him. We read incidents in the life of Jesus when he as the divinely appointed King prayed about difficult circumstances and instructed his opponents to consider their ways. There were also occasions when he encouraged his disciples by giving joy and peace to them, his joy, and his peace. Knowing that he rules from the highest throne gives us joy whatever opposition to his reign arises.
