To the Almighty, the Word of the Father, the perfect One Jesus Christ, for the sake of Thy mercy, never leave me, Thy servant, but always rest in me. Jesus, good Shepherd of Your sheep, do not betray me to the sedition of the serpent, and do not leave me to the desires of Satan, for the seed of aphids is in me. Thou, O Lord God worshiped, the Holy King, Jesus Christ, preserve me as I sleep with an unflickering light, by Thy Holy Spirit, with whom Thou hast sanctified Thy disciples. Grant, O Lord, to me, Thy unworthy servant, Thy salvation on my bed; enlighten my mind with the light of reason of Your holy Gospel, my soul with the love of Your Cross, my heart with the purity of Your word, my body with Your impassive passion; Preserve my thought with Your humility, and raise me up in time like Your praise. For Thou art glorified with Thy Beginningless Father and with the Most Holy Spirit forever. Amen.
He himself is perfect - being himself perfect (he is a participle of the verb to be: appearing, existing). Sedition - excitement, turmoil, rebellion. To the desire of Satan - to the will of Satan (to the will of Satan). The seed of an aphid is the seed of destruction. Unflickering - unfading. Give it - give it. The light of reason - here: the light of understanding. Your passionless passion - Your suffering, alien to passion. The time is like - the right time.
