What is the definition of Moral Good in God's omni-benevolence

A recent question asked about God's omni-benevolence, free will and God's ability to do evil. [My counter](https://christianity.stackexchange.com/a/95838/51977) to that was to look at Divine Command Theory which defines moral good as God's will, the questioner did ask further questions that made me wonder about this though. Would all conclusions of moral good that stem from the bible agree with DCT or is there a definition which sees moral good as something God also adheres to, external to themselves?
