7:1-10
We now get the first mention of Ezra, and various details about him.. The key thing is that he was well versed in the Law of Moses. The journey from Babylon took about four months. We are told that the Lord was with him, and that this was because he had devoted himself to the study and observance of the Law of the Lord. So he was qualified to be a teacher of the Law.
7:11-28
Ezra had a letter from Artaxerxes. The king was concerned that Ezra should ensure that the people are following the Law properly. He was also to take silver and gold artefacts, and to make proper sacrifices. It is interesting that the pagan king was so keen that the Law of God be properly implemented. The king's attitude encouraged Ezra. We are used to our governments being anti-God, or at best lukewarm. We should not be afraid to pray for a change of heart in our leaders.
