I thank thee, and praise thee, O thou God of my fathers, who hast given me wisdom and might, and hast made known unto me now what we desired of thee: for thou hast now made known unto us the king's matter.
I thank thee, and praise thee. He ascribes all the glory to God.
God of my fathers - thou hast shown thyself the same God of grace to me, a captive exile, as thou didst to Israel God of my fathers - thou hast shown thyself the same God of grace to me, a captive exile, as thou didst to Israel of old, and this on account of the covenant made with our "fathers" (Luke 1:54-55; cf. Psalms 106:45).
Who hast given me wisdom and might - thou being the fountain of both; referring to Daniel 2:20. Whatever wise ability I have to stay the execution of the king's cruel decree is thy gift.
And hast made known unto me now what we desired of thee: for thou hast now made known unto us the king's matter - "me ... we ... us." The revelation was given to Daniel, as "me" implies; yet with just modesty he joins his friends with him; because it was to their joint prayers, and not to his individually, that he owed the revelation from God.
Known ... the king's matter - the very words in which the Chaldeans had denied the possibility of any man on earth telling the dream ("There is not a man upon the earth that can show the king's matter, Daniel 2:10). Impostors are compelled by the God of truth to eat up their own words.
