A prayer of Habakkuk the prophet, according to Shigionoth.
There is no doubt but that the Prophet dictated this form of prayer for his people, before they were led into exile, that they might always exercise themselves in the study of religion. We indeed know that God cannot be rightly and from the heart worshipped but in faith.
This chapter is entitled a prayer of Habakkuk. It is a meditation with himself, an intercession for the church. Prophets were praying men; this prophet was so (He is a prophet, and he shall pray for thee, Gen 20:7); and sometimes they prayed for even those whom they prophesied against.
