John 6:27 contrasts perishable food with enduring food—same contrast between this water and living water.

John 6:35 directly answers the problem of John 4:13: whoever believes in Jesus will never thirst, contrasting the temporary satisfaction of earthly water with Christ's eternal provision.

Isaiah 65:13 contrasts God's servants who drink and are not thirsty with the wicked who thirst — highlighting that earthly water leaves one thirsty but God's provision satisfies.

Luke 16:24 shows the rich man in Hades begging for a drop of water — an example of unquenchable thirst that contrasts with the temporary thirst from earthly water in John 4:13.
