Destroy it down to its foundations!” Is 34:5–6; Ezk 35:2; Ob 10–14 8Daughter Babylon, doomed to destruction, happy is the one who pays you back what you have done to us.Jr 50:1–46; 51:1–64 9Happy is he who takes your little ones and dashes them against the rocks. Do nothing out of selfish ambition or conceit, but in humility consider others as more important than yourselves. https://temtube.com/#bible#bibleverse#subscribe
