Psalm 9:6
4 For you defended my just cause; from your throne you pronounced a just decision. 5 You terrified the nations with your battle cry. You destroyed the wicked; you permanently wiped out all memory of them. 6 The enemy’s cities have been reduced to permanent ruins. You destroyed their cities; all memory of the enemies has perished. 7 But the Lord rules forever; he reigns in a just manner. 8 He judges the world fairly; he makes just legal decisions for the nations.
LXX Psalm 9:6
5 For thou hast maintained my cause and my right; thou satest on the throne, that judgest righteousness. 6 Thou hast rebuked the nations, and the ungodly one has perished; thou hast blotted out their name for ever, even for ever and ever. 7 The swords of the enemy have failed utterly; and thou hast destroyed cities: their memorial has been destroyed with a noise, 8 but the Lord endures for ever: he has prepared his throne for judgment. 9 And he will judge the world in righteousness, he will judge the nations in uprightness.
Notes and References
"... It has been suggested that the translator of Psalms evaded the idea that God himself destroyed the wicked, and that he therefore changed the original text by reading the letters differently from the Masoretic text (עשרה דַבָא). However, if this were true, he would have been inconsistent for elsewhere in the LXX of Psalms God is pictured as personally destroying the wicked (Psalm 5:6–7; 143:12). It is therefore more likely that the difference between the Masoretic text and the Septuagint is based not on the translator’s tendentious change, but on variants that underlie the translation ..."
