This singing, unaccompanied by mechanical instruments of music, conforms to the music used in the apostolic church and for several centuries thereafter (Ephesians 5.19).
ການຮ້ອງເພງນີ້, unaccompanied ໂດຍເຄື່ອງມືກົນຈັກຂອງດົນຕີ, ສອດຄ່ອງກັບດົນຕີທີ່ນໍາໃຊ້ໃນສາດສະຫນາຈັກ apostolic ແລະສໍາລັບສັດຕະວັດແລ້ວຕໍ່ມາ (ເອເຟໂຊ 5: 19).
