5 The words which "the Lord said to Cain. . . 'The voice of thy brother's blood crieth to me from the earth'," ( Gen . 4, 10) are relevant today. For so the blood of the Hungarian people cries out to God. And even though God often punishes private individuals for their sins only after death, nonetheless, as history teaches, He occasionally punishes in this mortal life rulers of people and their nations when they have dealt unjustly with others. For He is a just judge.
