The answer is: The inhabitants were great and tall

Deut 1:28

The Israelites’ fear of entering the Promised Land because of its formidable inhabitants highlights the psychological struggles people face when confronted with seemingly insurmountable challenges. These towering “great and tall” adversaries represented not only a physical threat but also a deeper concern for the safety and security of their families and community. As they surveyed the land, prospects of formidable armies likely loomed larger than any divine promises they had already received.

Significantly, this narrative serves as a reminder of spiritual tests throughout biblical history. When facing giants—be they literal or metaphorical—many found courage in faith and support from their community. Think of David confronting Goliath; it started as David seeing his unlikely victory where others saw doom. Stories like this offer a resonant echo: faith can empower even the most unassuming amongst us to overcome gigantic obstacles.

Another interesting angle is the recurring theme of giants in various cultures and mythologies, suggesting that these fears resonate through human history. Fear is as common as hope. Deuteronomy invites readers to reflect not only on the challenges before them, but also on how might we prepare spiritually and mentally to face our giants today. Ultimately, learning from the Israelites' caution can help anyone facing intimidating situations—be it personal challenges or societal struggles—recognizing that sometimes the biggest barriers exist within our own minds.
