Shammua son of Zaccur represented the tribe of Reuben among the twelve spies sent by Moses to explore Canaan.
Biography
Numbers 13:4 names Shammua son of Zaccur as Reuben's representative. He was among the spies who explored Canaan for forty days. Apart from Joshua and Caleb, the spies' discouraging report led Israel toward unbelief and rebellion, though Scripture records no individual speech by Shammua.
Biblical Significance
Shammua belongs to the wilderness spy narrative whose majority report contributed to Israel's refusal to enter the promised land.
