Context: Isaiah 55 opens the climactic invitation section of the Servant Songs cycle (Isa 40-55). The immediate backdrop is the Fourth Servant Song (52:13-53:12) — the Servant's atoning death — and the barren-woman promise (54:1). Having purchased redemption, the Servant's work is now freely distributed: "Come, all you who are thirsty, come to the waters; and you without money, come, buy, and eat! Come, buy wine and milk without money and without cost!" The paradox is calculated: buy without money. The Hebrew shabar (buy grain) paired with the denial of keseph (silver) establishes the free-grace vocabulary the NT will appropriate. The invitation is universal in scope (hoy kol, "Ho, everyone") and free in cost, grounded in the Servant's payment already accomplished in the preceding chapter. Verses 1-5 universalize the Davidic covenant; verses 6-7 call for repentance; verses 8-11 ground the promise in God's reliable word; verses 12-13 paint the new-creation picture. The chapter is the OT's most explicit gospel-call.

OT-to-OT Development

• Isaiah 53:10-12 - The Servant's atoning death that purchases what Isa 55 now freely distributes. The two chapters are a unit: Isa 53 = the price paid; Isa 55 = the invitation to come "without cost."
• Isaiah 12:3 - "With joy you will draw water from the springs of salvation" — Isa 55:1 specifies who may draw: anyone who thirsts.
• Isaiah 44:3 - "I will pour water on the thirsty land" — Isa 44:3 is the promise of outpouring; Isa 55:1 is the summons of the thirsty to receive.
• Jeremiah 2:13 - Jeremiah diagnoses Israel's refusal to come; Isaiah had already extended the invitation freely.

Connections

  • Isaiah 53:10-12 - Servant's atoning payment that funds the free invitation
  • Isaiah 12:3 - joyful drawing from springs of salvation
• FROM OT:
  • Isaiah 44:3 - water/Spirit promise
  • Jeremiah 2:13 - broken cisterns contrast
• FROM NT:
  • Matthew 11:28 - "Come to Me, all you who are weary and burdened" (deuterographic echo)
  • John 4:10-14 - "If you knew the gift of God... He would have given you living water" (free)
  • John 7:37 - "If anyone is thirsty, let him come to Me and drink"
  • Revelation 21:6 - "To the thirsty I will give freely from the spring of the water of life"
  • Revelation 22:17 - "the one who desires the water of life drink freely" — δωρεάν ("freely") renders the free-offer sense of Isa 55:1's "without money and without cost"

Christological Connection: Isaiah 55:1 supplies the form of Jesus' own invitation and the substance of Revelation's closing summons. The link to John 7:37 runs through the shape of the summons — thirst addressed (צָמֵא ṣāmēʾ), waters offered, price refused — rather than through a rare shared word: the only lexeme common to the two in Greek is διψάω (dipsaō, "thirst"), which is ordinary NT vocabulary and carries no weight on its own. The tie to Revelation is the tighter of the two. Rev 22:17 takes up Isa 55:1's free offer closely (the thirsty, the water, and δωρεάν, "freely," for Isaiah's "without cost") and places it on the lips of the Spirit and the Bride as the Bible's final evangelistic cry — a deliberate canonical bookend with Isaiah. Jesus' John 7:37 cry ("If anyone is thirsty, let him come to Me") replaces the implicit OT subject (come to Yahweh, the fountain of Jer 2:13) with the explicit christological subject (come to Me) — a staggering identity claim: Jesus positions Himself as the fountain Yahweh declared Himself to be. The "without cost" logic of Isa 55:1 is funded by the price Christ paid in Isa 53: the Servant's substitutionary atonement ("He was pierced for our transgressions," 53:5) is what allows the invitation to be free ("without money and without cost," 55:1). This is gospel-logic in its purest OT form: the cost is borne by the Servant so the thirsty may drink without cost. The escalation: Isaiah invites to the waters → Christ identifies Himself as those waters → Revelation invites to the spring of the water of life flowing from the throne. What Isaiah offered freely because the Servant would pay, Christ now offers freely because He has paid.

Connection Method(s): Promise-Fulfillment (primary) + Contrast — Isaiah's free invitation to the thirsty funded by the Servant's atoning payment (Isa 53 → 55) directly underwrites Jesus' invitation (John 7:37) and Revelation's closing summons (Rev 22:17); the gospel's "without cost" is rooted in Isaiah's vocabulary. Contrast with Jeremiah 2:13's broken cisterns: Isaiah invites; Israel refuses; Christ renews the invitation.
