Leviticus 25:4 commands the land Sabbath that raises the question in verse 20 — immediate context.

In Psalm 78:19, Israel questions whether God can provide food in the wilderness, directly echoing the same doubt about provision during the sabbatical year.

In Psalm 78:20, the doubters ask if God can give bread after providing water, paralleling the worry in Leviticus about having enough to eat.

In Matthew 6:25-34, Jesus teaches not to worry about food and clothing, directly addressing the same anxiety about sustenance as in the sabbatical year.

In Luke 12:29, Jesus commands not to be anxious about food, directly matching the concern in Leviticus about what to eat during the fallow year.

In Philippians 4:6, Paul tells believers not to be anxious but to pray, which directly counters the worry about provision seen in Leviticus.

Exodus 23:11 gives the sabbatical year command that prompts this question — the law behind the concern.

Matthew 6:31 quotes the same worried question 'What shall we eat?' — Jesus directly addresses this anxiety.

Matthew 6:33 gives the answer: seek God's kingdom, and provision will follow, just as God promises blessing in Leviticus.
