2 Corinthians 8:15 → Exodus 16:18

Paul quotes Exodus 16:18, where God's miraculous manna provision ensured wilderness equality — those gathering much had no surplus, those gathering little had no lack. Paul applies this by analogy to church generosity: just as manna created equality in Israel's wilderness journey, Christian giving should create economic equality in the church. This is a moral correspondence, not a shadow-and-substance type — there is no christological antitype here, but an ethical pattern read from the wilderness regulation. And it is grace-shaped, not merit: the manna fell on grumblers, unearned and daily, so the generosity it models is the overflow of received grace (cf. 2 Cor 8:9 — "though He was rich, yet for your sakes He became poor, so that you through His poverty might become rich"). The manna principle prohibits hoarding (it spoiled overnight), tests faith in God's continued provision, and demonstrates corporate identity — one body caring for all members. The Jerusalem collection embodies this: Gentile believers helping Jewish believers, furthering unity while trusting God's supply.
