Bible Commentary
Psalm 36
Psalm 35 concluded with reference to the prosperity of God's servant--i.e., David (verse 27). Now, the superscription of Psalm 36 refers to David as "the servant of the LORD." The psalm begins by addressing the nature of wickedness, but this is soon contrasted with God's faithfulness and righteousness and His rewarding of His servants such as David with an abundance of true prosperity.
The word "oracle" in verse 1 can simply mean "utterance." The actual order of the verse is "An oracle of transgression of the wicked within my heart." Some see "of the wicked" as actually meaning "to the wicked." However, the psalm's focus on God rewarding the righteous and the request for the righteous to be kept from wickedness goes against that being the aim of the psalm. Some translations give "within my heart" as "within his heart," thinking the wicked person is intended. However, the Hebrew lebi in the Masoretic Text does mean "my heart." Simply put, David is expressing his deep thoughts about the sinful way of the wicked.
David's consideration of the sinful course of the wicked (verses 2-4) is followed by contemplation of God's mercy, faithfulness, righteousness, justice and unfailing love (verses 5-7). "The contrast of these verses with the previous ones is extreme. Just as the revelation of the depravity in vv. 1-4 is awful, the revelation of the Lord's love is even more wonderful.... The contrasts continue with David ranging from the highest mountains to the depths of the sea to describe the perfect character of God. The height of the great mountains can be compared to how great God's righteousness is; the depths of the seas can be compared with how mysterious and inaccessible God's true judgments are" (Nelson Study Bible, note on verses 5-6).
Like nestlings seeking shelter and nourishment from a mother bird, so may people find protection and provision from God (verse 7). If the wicked would only cease from their headlong pursuit of fleeting self-gratification through sin and turn to God, they would find true and abundant satisfaction through the fullness of life in His family (verse 8). For the righteous "drink from the river of [God's] pleasures." What a beautiful word picture this is--of an endless, flowing supply of joyful experience forevermore! This river flows from the "fountain of life"--God's Holy Spirit bringing eternal salvation and all its rewards (see also Isaiah 12:3; Isaiah 55:1-2; Jeremiah 2:13; John 7:37-39).
It is only in God's "light" that we "see light" (Psalm 36:9). In context, this may mean that we don't even really know what it means to live and be happy until we experience life in the way God intended. Rather than groping in the blindness of human plotting to find our way, the truth of God reveals the path to ultimate and lasting bliss. On the other hand, the idea here could be that it is through God shining on us (favoring and guiding us) that we will live to see a bright outcome for our lives (compare Psalm 37:3-6; see also Isaiah 60:19-20).
In closing, David prays that God's loyal love will continue for those who "know" Him and are thereby "upright in heart" (Psalm 36:10). Indeed, truly knowing God implies more than knowing about Him. It means having a relationship with Him, which is based on obedience to His laws (see 1 John 2:3-4; John 15:14). To have a relationship, we have to spend quality time with God through prayer, Bible study and contemplative meditation. Even fellowship with likeminded believers is an important way to fellowship with the Father and Christ (1 John 1:3)--as the Father and Christ dwell in faithful believers through the Holy Spirit.
David further asks for protection from the wicked who refuse to submit to God's way (Psalm 36:11)--perhaps thinking of some who were scheming to overthrow him. And he concludes with a final consideration (or prophetic glimpse) of the doom of the wicked (verse 12), which we see more about in the next psalm.
