Why was Moses the most sinful man in the Bible?

Moses is often considered one of the most significant figures in The Bible, but his actions reveal moments of disobedience and anger that some interpret as sinful. For instance, he struck the rock to bring forth water instead of speaking to it as God commanded, which led to God's decision that he would not enter the Promised Land (Numbers 20:7-12). Additionally, his initial reluctance to lead the Israelites and his outburst of anger when he broke the tablets of the Ten Commandments also highlight his human flaws. However, it's essential to view Moses within the broader context of his leadership and faithfulness to God despite these failings.
