The phrase "Κύριε Ἰησοῦ Χριστέ, ἐλέησόν με" (Kyrie Iesou Christe, eleison me) is a Greek phrase that translates to "Lord Jesus Christ, have mercy on me" in English. This phrase is often associated with Christian prayer, particularly in Eastern Orthodox Christianity.

In Christian spirituality, it is a simple yet profound plea for divine mercy and grace. Believers use this prayer to express their need for God's forgiveness, help, and guidance. It's a way to acknowledge one's dependence on Christ's mercy and a desire for His compassion and intervention in their life.

The repetition of this prayer, often in a rhythmic and meditative manner, is known as the "Jesus Prayer." Many Christians use it as a form of contemplative or meditative prayer to draw closer to God and seek His presence and mercy in their daily lives. It has a rich tradition in Orthodox Christian spirituality and is also used in other Christian denominations as a means of seeking spiritual growth and connection with God.
