stop it dude shits out of context ......O Daughter of Babylon, doomed to destruction, happy is he who repays you for what you have done to us- psalms 137.8
Happy shall he be that taketh ... - Margin, as in Hebrew, rock. This refers to what was not uncommon in ancient warfare, as it is now among savage tribes - the indiscriminate slaughter of those of all ages, and of both sexes, in war. It was expressly foretold of Babylon that this would occur (see Isaiah 13:16, and the notes at that place), and there may be a reference here to that prediction, and the psalmist may mean to say that the man would be accounted happy, or would be happy, who wreaked vengeance on Babylon in carrying out that prophecy. The idea is, "This will certainly occur, for it is foretold, and happy or fortunate will he be who is the instrument in fulfilling it." Compare 2 Kings 8:12; Nahum 3:10; Hosea 13:16. See also Homer, II xxii. 63,373, following It is impossible to reconcile such barbarous customs with the idex of "honorable war," or with the principles of war as carried on among "civilized" nations now.
