Then Menahem smote Tiphsah, and all that were therein, and the coasts thereof from Tirzah: because they opened not to him, therefore he smote it; and all the women therein that were with child he ripped up—2 Kings 15:16
Ripping open pregnant women's bellies? In the Bible. Condemning slavery? Not in the Bible.
Oh, and what was that about God's love for little unborn fetuses?
