Context: Isaiah 2:2-3 envisions the eschatological pilgrimage of nations to Zion: "In the last days the mountain of the LORD's house will be established as the chief of mountains...and all nations will stream to it. Many peoples will come and say, 'Come, let us go up to the mountain of the LORD...that He may teach us His ways.'" Isaiah 56:3, 6-7 addresses foreigners directly: "Let not the foreigner who has joined himself to the LORD say, 'The LORD will surely separate me from His people'...The foreigners who join themselves to the LORD, to minister to Him, to love the name of the LORD...these I will bring to My holy mountain...My house shall be called a house of prayer for all peoples."

OT-to-OT Development:

• Isaiah's vision develops the Abrahamic promise: "In you all the families of the earth shall be blessed" (Gen 12:3). What was promise in Genesis becomes vision in Isaiah.
• Ruth embodied this prophetic hope—one "foreigner" (נָכְרִיָּה, Ruth 2:10) who "joined herself" to YHWH. Isaiah generalizes Ruth's story to cosmic scope.
• The phrase "house of prayer for all peoples" (56:7) is cited by Jesus when cleansing the temple (Mark 11:17), demonstrating NT fulfillment.

Connections:

• TO OT: Genesis 12:3 (all families blessed), Ruth 1:16-17 (Ruth joins YHWH), Psalm 87:4-6 (nations born in Zion)
• FROM OT: Zechariah 8:20-23 (nations seeking the LORD), Zechariah 14:16 (nations go up to worship)
• FROM NT: Mark 11:17 (house of prayer for all nations), Acts 2:5-11 (Pentecost—every nation), Ephesians 2:11-22 (Gentiles included), Revelation 7:9 (multitude from every nation)

Christological Connection: Isaiah's prophecies find fulfillment through Christ. (1) Nations Streaming to Zion: Christ draws all people to Himself: "I, when I am lifted up from the earth, will draw all people to Myself" (John 12:32). (2) "Let Not the Foreigner Say...": The fear of exclusion is answered in Christ—"In Christ Jesus you who once were far off have been brought near" (Eph 2:13). (3) "House of Prayer for All Peoples": Jesus cleansed the temple citing Isaiah 56:7 (Mark 11:17). The church, Christ's temple, fulfills this—multiethnic worship. (4) "To Love the Name of the LORD": Gentiles who love Christ's name are included: "Everyone who calls on the name of the Lord will be saved" (Rom 10:13). (5) Ruth as Prototype: One Moabitess demonstrated what Isaiah prophesied—foreigner joining YHWH, loving His name, serving His people. Ruth's personal story becomes Isaiah's universal vision, fulfilled in Christ's global church.

Connection Method(s): Promise-Fulfillment; Longitudinal Theme — Isaiah's prophecies of nations streaming to Zion and foreigners joining the LORD are fulfilled through Christ who draws all peoples to Himself (John 12:32), with Jesus citing Isaiah 56:7 when cleansing the temple (Mark 11:17).
