Verse 24 explains the valley was named Eshcol because of the cluster cut there—directly etymological from the event in verse 23.

Verse 20 instructs the spies to bring back fruit; verse 23 fulfills that command—a direct narrative sequence.

Verse 28 reports the negative aspects of the land after the positive fruit—part of the same spy report, contrasting the land's goodness with its strong inhabitants.

Numbers 32:9 recalls the same spy mission to the Valley of Eshcol, adding that the spies discouraged Israel from entering the land.

Deuteronomy 1:24 gives a parallel account of the spies exploring the Valley of Eshcol—the same event from a different perspective.

Deuteronomy 1:25 continues the parallel account, mentioning the fruit brought from Eshcol—directly echoing the cluster of grapes in the main verse.

Joshua 11:21 records destroying Anakim at Hebron — the same region where the spies brought fruit (Eshcol near Hebron). Shows later conquest of the land.

Joshua 15:14 tells of Caleb driving out the sons of Anak from Hebron — the very spy who brought the fruit now conquers the land.

Hosea 9:10 uses 'grapes in the wilderness' and 'first fruit on the fig tree' — echoes the fruit the spies brought as a symbol of God's initial blessing.

Joel 1:12 describes the vine, fig, and pomegranate withering — the same fruits the spies brought as evidence of abundance, now a sign of judgment.

2 Corinthians 5:5 calls the Spirit a 'guarantee' — just as the cluster of grapes was a guarantee of the land's fruitfulness, the Spirit is our guarantee of future glory.
