Matthew 17:5 → Deuteronomy 18:15

Matthew's Transfiguration voice — "This is My beloved Son, in whom I am well pleased. Listen to Him!" (Matt 17:5) — closes with the command of Deuteronomy 18:15: "You must listen to him" (LXX αὐτοῦ ἀκούσεσθε). Matthew's ἀκούετε αὐτοῦ inverts the LXX's pronoun-first order (Luke 9:35 preserves it), making Mark/Luke the tighter text-form witnesses — but Matthew is the fullest form of the utterance and the form the church has preached for two millennia: in a single sentence the Father layers Ps 2:7 royal sonship ("This is My Son"), Isa 42:1 Servant-delight ("in whom I am well pleased," repeating the baptismal voice of Matt 3:17), and the Deut 18:15 prophetic authorization ("Listen to Him!") — King, Servant, and Prophet named in one breath, in the presence of Moses himself (v. 3). Spurgeon preached exactly this identification (MTP #1727, 1883): "'Hear ye him,' which is a repetition of Deuteronomy 18:15, where Moses saith, 'The Lord thy God will raise up unto thee a Prophet from the midst of thee, of thy brethren, like unto me; unto him ye shall hearken'; or as Stephen puts it, 'him shall ye hear.'" Matthew alone then narrates the aftermath: "When the disciples heard this, they fell facedown in terror" (17:6) — the very Horeb terror that first occasioned the promise (Deut 18:16) — and it is the Prophet himself who "came over and touched them. 'Get up,' He said. 'Do not be afraid'" (17:7). The whole logic of Deuteronomy 18 is enacted in three verses: the unmediated voice produces terror; the promised Mediator turns that terror into nearness. The telos: the command to listen is not summons to a tribunal but invitation to the One in whom the Father delights — to hear this Prophet is to be touched by him and told "do not be afraid," which is what the promise of a mediator was mercy for from the beginning.
