Daniel 10:1
1In the third year of Cyrus king of Persia a message was revealed to Daniel, whose name was called Belteshazzar; and the message was true, even a great warfare. He understood the message, and had understanding of the vision.
A word is revealed in Cyrus’s third year, and it is true. Belteshazzar is the court-name; Daniel is still the prophet. Wesley treats chapters 10–12 as one vision: this chapter is introductory humiliation. “Great warfare” is the burden of the word for the people.
God reveals, and Daniel actually understands. The gift is no illusion; so is the hearer. Revelation is not a private cipher. Grace opens the word to a servant who must still receive it.
Calvin: the word itself was most true, although the time of fulfillment should be long. Certainty does not mean haste. If a promise tarries, wait for it. The double name is a monument among Medes and Persians that this Belteshazzar still belongs to Israel’s God. Understanding accredits what follows.
God gives a stable word and a long horizon. “He understood” invites the church to ask for light rather than to despair at first obscurity. The conflict is in His timetable, not ours to chart.
