Psalm 36 is kind of a cross between a lament psalm and a meditative psalm.
The Five Elements of the Structure of a Lament Psalm:
1) Lament
2) Invocation
3) Confidence
4) Praise
5) Petition

We must maintain the elements of the great objectives of meditation:

The lament, where David reveals the problem he needs God’s help to work through, then there’s praise to God, invoking God for help, asking God for whatever the psalmist needs, and then expressing confidence in the Lord. Psalms 36. It is uncertain when, and upon what occasion, David penned this psalm, probably when he was struck at either by Saul or by Absalom; for in it he complains of the malice of his enemies against him, but triumphs in the goodness of God to him. Hymns based on Psalm 36 include in English ” Praise to the Lord, the Almighty ” and “Immortal, Invisible, God Only Wise”.

It reads in Psalm 36:1-12
“For the director of music. Of David the servant of the Lord.”
I have a message from God in my heart concerning the sinfulness of the wicked: There is no fear of God before their eyes. In their own eyes they flatter themselves too much to detect or hate their sin. The words of their mouths are wicked and deceitful; they fail to act wisely or do good. Even on their beds they plot evil; they commit themselves to a sinful course and do not reject what is wrong. Your love, Lord, reaches to the heavens, your faithfulness to the skies. Your righteousness is like the highest mountains, your justice like the great deep. You, Lord, preserve both people and animals. How priceless is your unfailing love, O God! People take refuge in the shadow of your wings. They feast on the abundance of your house; you give them drink from your river of delights. For with you is the fountain of life; in your light we see light. Continue your love to those who know you, your righteousness to the upright in heart. May the foot of the proud not come against me, nor the hand of the wicked drive me away. See how the evildoers lie fallen, thrown down, not able to rise!
