Prophetic verses

After studying the book of Revelations, I was again reading Psalms and saw correlations. Revelations 13 talks about a seven headed beasts which represents Satan and kingdoms controlled by him. There are blasphemies against God. Pslams 74:10 asks, "O God, how long shall the enemy blaspheme Thy name?" Then in verse 13,and 14 the comforting assurance, "Though didst divide the sea by thy strength; thou brakest the heads of the dragons in the waters. Thou brakest the heads of leviathan in pieces" I don't know what all the images in Revelations specifically represent but I do know that the Lord will triumph.
