In his book, “Dictionary of Biblical Theology,” Xavier Leon-Dufour points out that in the OT, the Israelite understanding of divine kingship differed from that of other ancient Eastern kingdoms in an essential way: Yahweh has a covenant with his people. He desires his reign to be recognized by obedience to the Law. His reign is of the heart, a moral code, not a political one. (p 292)
In today’s gospel, after his baptism, Jesus has moved to Capernaum, on the Sea of Galliee and beings his public ministry by declaring the “Kingdom of heaven is at hand.” Then he began teaching in the synagogues, proclaiming the gospel of the Kingdom, and curing people. A sign, it seems, that the kingdom had indeed come in the person of Jesus. It has broken into history, into time and space.
