10:2 Was mourning - Because he foresaw the many calamities that would befall the Jews for their sins, especially for destroying the Messiah, and rejecting his gospel.
10:1-9. This chapter relates the beginning of Daniel's last vision, which is continued to the end of the book. The time would be long before all would be accomplished; and much of it is not yet fulfilled. Christ appeared to Daniel in a glorious form, and it should engage us to think highly and honourably of him. Let us admire his condescension for us and our salvation. There remained no strength in Daniel. The greatest and best of men cannot bear the full discoveries of the Divine glory; for no man can see it, and live; but glorified saints see Christ as he is, and can bear the sight. How dreadful soever Christ may appear to those under convictions of sin, there is enough in his word to quiet their spirits.
