Who did Daniel pray for when he said, 'We have sinned'?
When Daniel said 'We have sinned,' he was praying for himself and his people, the nation of Israel. The context explains he was speaking about himself and Israel, who were in captivity because of their rebellion and sinfulness against God's precepts and judgments.
Les explains that Daniel, a young Jew in captivity far from home in a pagan land, prayed on behalf of his people, Israel. In chapter 9, Daniel confesses, 'we have sinned, we have committed iniquity... we have done wickedly, and we've rebelled, even by departing from thy precepts and from thy judgments.' He identifies with his nation, acknowledging their rebellion and sinfulness as the reason for their captivity. Earlier, Daniel prayed three times a day with windows open toward Jerusalem, giving thanks before God, showing that prayer includes thanksgiving, not just asking.
