Bible Expert: One of the most famous verses in Psalms 137 is verse 9, which says "Happy shall he be, that taketh and dasheth thy little ones against the stones." This verse is often interpreted as a call for vengeance against Babylon, although some scholars have argued that it is a metaphor for the destruction of Babylon.
