Also I in the first year of Darius the Mede, even I, stood to confirm and to strengthen him.
This chapter is an enlargement of the eighth.
Also I ... even I - the angel, who was "like the appearance of a man" (Daniel 10:18).
In the first year of Darius - Cyaxares II, the year of the conquest of Babylon (Daniel 5:31). Cyrus, who wielded the real power, though in name subordinate to Darius, in that year promulgated the edict for the restoration of the Jews, which Daniel was at the time praying for (Daniel 9:1-2; Daniel 9:21; Daniel 9:23).
Stood - implying promptness in helping, (Psalms 94:16, "Who will stand up for me against the workers of iniquity?")
To confirm and to strengthen him - namely, Michael; even as Michael (Daniel 10:21, margin, 'strengtheneth himself with me') helped the angel, both joining their powers in behalf of Israel (Rosenmuller). Or, Darius, the angel 'confirming him' in his purpose of kindness to Israel.
