It was the first month of the 40th year of wandering in the wilderness. Still grieving over the death of his beloved sister Miriam (Numbers 20:1), Moses had to cope with the rebellion of his people. The second generation of Israelites who had been freed from captivity was about to enter the Promised Land.

But they were committing the same mistakes of the previous generation—complaining and thinking of going back to Egypt (Numbers 20:2-5, 14:1-4; Exodus 17:1-4). If they rejected God a second time, they could well end up wandering in the desert for another 40 years! A feeling of fear and trepidation seized and overwhelmed Moses.

Year after year, he had somehow gotten the stiff- necked ingrates under his leadership through one crisis after another. But all Moses ever got for his efforts were more complaints and criticisms. Now, in deep grief and anger, he shouted, “Listen . . . you rebels! . . . Must we bring you water from this rock?” (Numbers 20:10). Drawing attention to himself, Moses disobeyed God and struck the rock twice (Numbers 20:11). His prideful disobedience and negative attitude dishonored God. As a result, Moses was not permitted to enter the Promised Land (Numbers 20:12).

The psalmist commented, “They made Moses angry, and he spoke foolishly” (Psalm 106:33). When we’re angry, we tend to utter cutting words—harsh and rash ones—which we will certainly regret later. That’s why we must learn to control our anger (Ecclesiastes 7:9; Proverbs 14:29, 16:32). The apostle James gives us this timely advice: “You must all be quick to listen, slow to speak, and slow to get angry. Human anger does not produce the righteousness God desires” (James 1:19-20). Temper that temper!
