What does the Bible say about disobeying God's commands?

In 1 Kings 13, we see the tragic account of a man of God who initially obeyed God's command but was deceived into disobedience by an old prophet. This man was instructed not to eat or drink in the place where he prophesied, yet he succumbed to temptation and disobeyed. The result was a judgment from God, highlighting the seriousness of adhering to His word. This narrative serves as a warning that we must remain vigilant against deception, as even well-meaning individuals may lead us away from God's truth.
