King James Bible
"Yet in this thing ye did not believe the LORD your God,"
Moses points to a specific failure—Israel's refusal to enter the Promised Land after the negative report from ten spies. The phrase emphasizes that despite God's past faithfulness, the people failed at this crucial moment of testing. The core accusation is unbelief in Yahweh himself, not merely doubt about circumstances. This distrust contradicted their covenant relationship and ignored God's demonstrated power in delivering them from Egypt, revealing that their rebellion was fundamentally a crisis of faith.
