No it does not say it came from God - the Bible does not teach that every decision made by a king is from God - this verse says God is ABLE to influence kings (that is not the same thing as stating every action of theirs is influenced by God). There are many examples of God overruling the actions and decrees of national leaders to get His will done.

I do believe in the sovereignty of God - and believe He is in control - that nothing happens unless He causes or allows it; however, that is not the same thing as stating everything that happens is by His direct decree.
