What does the Bible say about prayer and confession?

In the book of Daniel, specifically chapter 9, Daniel exemplifies the practice of prayer and confession when he intercedes on behalf of his people, acknowledging their sins and pleading for God's mercy. He cries out, 'We have sinned and have committed iniquity,' showing both humility and a recognition of the dire need for grace (Daniel 9:5). This pattern is echoed throughout Scripture, illustrating how sincere confession and earnest prayer can lead to restoration and forgiveness from God.
