Romans 8:36

Even as it is written, For thy sake we are killed all the day long; We were accounted as sheep for the slaughter. [Psalms 44:22. This Psalm is supposed to have been written during the Babylonish captivity, and that it is a correct description of the state of the Jew in that day, we may readily conceive from details given in Daniel and Esther. But the Psalm was also prophetic. As the Jew suffered because of the peculiar religion which God had bestowed upon him, so also did the Christian; and in both cases the enemies of the revealed religions looked upon the worshipers as people who were to be killed as a matter of course, without compunction or pity, just as sheep are slain for sacrifice or for the market.]
