One of the most beautiful Psalms begins with the memorable lines…

“By the rivers of Babylon, there we sat down, yea, we wept, when we remembered Zion.”

Psalm 137:1 (AKJV)

But then, beauty turns grisly…

“Happy shall he be, that taketh and dasheth thy [Babylonian] little ones against the stones.”

Psalm 137:9 (AKJV)
