Daniel receives a vision revealing a great conflict between good and evil that would affect God's people in the last days. Though the vision was given in the third year of Cyrus' rule, its meaning was not fully understood until later. Daniel mourned and fasted for three weeks seeking greater understanding of what he had seen regarding the restoration of God's people and sanctuary. His strict diet and abstinence from luxuries during this time helped sharpen his mind to discern the Holy Spirit's revelations. The vision in chapter 10 provides further explanation of the restoration outlined in Daniel 8-9.
