I see what you did there. Decree
and determined (v) would not be synonyms, however decreed (v) and determined (v) would be synonyms. So would decree (v) and determine (v). So, no falsehoods at all. This is you saying you want a thesaurus for Christmas without directly asking for a thesaurus for Christmas. I think I noted that I had looked it up in a thesaurus, which was clear that they are synonyms. I also presented definitions that showed they are synonyms.
Decree can be a noun, but it can also be a verb. It isn't that difficult to follow. I decree that that person is not allowed to... (a verb). I gave a decree that this person... (a noun). In the case of Daniel 9, it is a verb. Command, decree, determine, or if being literal, to cut off/divide.
You should be able to present a valid compelling argument at this level, which would tell me it may be worth spending my precious, little time with books and videos. However, this is not at all compelling. Especially when you start up with a blatant falsehood.
