Pour out thy wrath upon the heathen that have not known thee, and upon the kingdoms that have not called upon thy name.
Pour out thy wrath upon the heathen that have not known thee - even as they have "shed" or 'poured out' (the same Hebrew) the blood of thy people like water round about Jerusalem (Psalms 79:3). Compare also Psalms 79:10. The nations to be judged are not all the pagan, but those only which rise up against Israel. So it shall be in the judgment to be inflicted on those kings and peoples who shall be seduced by Antichrist to join in "the battle of that great day of God Almighty" (Revelation 16:14; Zephaniah 3:8).
Not called upon thy name. To 'call upon the name of God,' in Scripture conception, is, from one's experimental knowledge of His attributes, His love, power, and faithfulness, to apply heartily to Him for salvation.
