Matthew Henry Commentary on the Bible
Psalms 109 - Introduction
* David complains of his enemies. (1-5) He prophesies their destruction. (6-20) Prayers and praises. (21-31) #1-5. It is the unspeakable comfort of all believers, that whoever is against them, God is for them; and to him they may apply as to one pleased to concern himself for them. David's enemies laughed at him for his devotion, but they could not laugh him out of it.
