Had the disciples any doubt that Jesus would someday come to reign in glory (16:27), he promises them a proleptic vision of his glory in the present (16:28). In a narrative that resembles Moses' revelation on Mount Sinai, the disciples become witnesses like Moses of Jesus' divine glory (17:1-8). The six days (17:1) probably allude to Exodus 24:15-18 (see, for example, Mauser 1963:111). The bright cloud (Mt 17:5; Ex 24:15) and other features of the narrative likewise recall the revelation on Mount Sinai. The appearance in Matthew 17:3 of the literal Moses and Elijah (both of whom had experiences with God on Mount Horeb) invite the reader to consider the other allusions to Moses (17:2-5) and Elijah (17:10-13) later in the narrative.
