In this section the emphasis lies on the need for God to act for David.
35:19-21 Winking at one another David's enemies communicated their sneaky intention to trap the psalmist in their plot. They were lying to turn others against him. They were also giving false testimony concerning his actions.
35:22-26 Their claims of having seen David do something bad were groundless, but God had seen their evil actions. David called God to end His silence and act for him. By vindicating David, God would frustrate the attempts of the wicked to triumph over the upright.
35:27-28 In closing David asked God to cause his supporters to give glory to the Lord for vindicating His righteous servant. When deliverance came David too would praise God for His righteous dealings.
The people of God can appeal for vindication when others falsely accuse us of doing evil, and we can count on God's deliverance in the future because He is just.
