Psalms Trivia:
137:1-9
1 By the rivers of Babylon, there we sat down, yea, we wept, when we remembered Zion.
2 We hanged our harps upon the willows in the midst thereof.
3 For there they that carried us away captive required of us a song; and they that wasted us required of us mirth, saying, Sing us one of the songs of Zion.
In Babylon, our captors said to us,
Sing us a song.
4 How shall we sing the LORD's song in a strange land?
5 If I forget thee, O Jerusalem, let my right hand forget her cunning.
6 If I do not remember thee, let my tongue cleave to the roof of my mouth; if I prefer not Jerusalem above my chief joy.
7 Remember, O LORD, the children of Edom in the day of Jerusalem; who said, Rase it, rase it, even to the foundation thereof.
But how can we sing God's song in a strange land?
8 O daughter of Babylon, who art to be destroyed; happy shall he be, that rewardeth thee as thou hast served us.
9 Happy shall he be, that taketh and dasheth thy little ones against the stones
You'll watch as we happily smash your little children and babies against the stones. [1]
God will send people to smash little Babylonian children against stones to punish the Babylonians for enslaving the Israelites during the Babylonian captivity.
These happy ("blessed" in the ESV) children smashers are God's instruments for carrying out his vengeance.
