There is some very good contrast in Psalm 71. First with verse 2, where David asks God to bring confusion and shame to his enemies, May those who seek my life be put to shame and confusion; may all who desire my ruin be turned back in disgrace. Then in verse 4, where David now asks God to bring joy to those who seek Him, But may all who seek you rejoice and be glad in you; may those who love your salvation always say, “Let God be exalted!”
