The voice of God in the burning bush scene was provided by Charlton Heston, but the voice of God in the tablet-giving scene was provided by a voice actor with a deep bass voice, Jesse Delos Jewkes, who was a member of the Mormon Tabernacle Choir. Additionally, Jewkes' voice was enhanced by the use of the vox humana stop of the Salt Lake Tabernacle organ. De Mille, who was good friends with LDS church president David O. McKay, asked for and received permission to record the organ from President McKay.
