As part of the Greek formula Kyrie eleison (“Lord, have mercy”), the word is used as a preliminary petition before a formal prayer and as a congregational response in the liturgies of many Christian churches. The prayer, "Kyrie, eleison," "Lord, have mercy" derives from a Biblical phrase. Greek ἐλέησόν με κύριε "have mercy on me, Lord" is the Septuagint translation of the phrase חָנֵּנִי יְהוָה found often in Psalms (4:1, 6:2, 9:13, 25:16, 27:7, 30:10, 31:9, 51:1, 86:16, 123:3)
