Contextual application
Prepare the way of the LORD
Old Testament · Isa 40:1–5
Isaiah announces comfort after judgment. A wilderness road pictures YHWH coming to restore His people; His glory will be revealed. The original promise concerns God’s return and Israel’s restoration, not merely a prediction of a roadside preacher.
New Testament · Mark 1:1–8
Mark begins with Jesus Christ and describes John as the wilderness voice preparing the Lord’s road. The one who then comes is Jesus. Mark 1:2 also combines messenger language from Malachi 3:1 with wording resembling Exodus 23:20; the attribution to Isaiah introduces the larger prophetic sequence.
Hebrew, Septuagint, and Greek
Hebrew wording
דֶּרֶךְ יְהוָה
Derekh YHWH: the way of YHWH. Isaiah names Israel’s God, not an unnamed human traveler.
Septuagint excerpt
ἑτοιμάσατε τὴν ὁδὸν κυρίου
Prepare the way of the Lord. Isaiah 40:3’s Greek wording is retained in Mark’s quotation.
New Testament excerpt
ἑτοιμάσατε τὴν ὁδὸν κυρίου
Jesus’ arrival enacts the promised coming of Israel’s God. This is a narrative identification through Scripture, not an explicit sentence saying “Jesus is YHWH.” Read with Mark’s forgiveness, authority, and Sonship narratives, it contributes to the cumulative case.
Interpretive qualification
God can come to act through His Messiah, so the allusion alone does not settle every question about divine nature. Mark’s composite quotation and the change in who prepares whose road require contextual explanation rather than treating a single title as proof.
