The Hebrew name Achiman combines ach (brother) and man (gift, or possibly 'man'). It means 'my brother is a gift' or possibly 'brother of a portion.' The name belonged to one of the three giant sons of Anak who inhabited Hebron and terrified the Israelite spies.
Achiman, Sheshai, and Talmai — the three sons of Anak — were the fearsome giants of Hebron whom the ten faithless spies described as making Israel look like grasshoppers (Numbers 13:22, 33). Their presence in the land was used by the fearful spies as a reason for unbelief. Yet Caleb silenced the people with faith, declaring that the LORD was with them (Numbers 13:30). Later, Caleb himself drove out Achiman, Sheshai, and Talmai (Joshua 15:14). The story of these giants becomes a lesson in the triumph of faith over fear — what loomed as an impossibility was defeated by one man's trust in God.
