Why do the heathen rage, and the people imagine a vain thing?
2 The kings of the earth set themselves, and the rulers take counsel together, against the Lord, and against his anointed, saying,
3 Let us break their bands asunder, and cast away their cords from us.
That is, which will prove to be a vain thing, or a thing which they cannot accomplish. It cannot mean that they were engaged in forming plans which they supposed would be vain - for no persons would form such plans; but that they were engaged in designs which the result would show to be unsuccessful. The reference here is to the agitation among the nations in respect to the divine purpose to set up the Messiah as king over the world, and to the opposition which this would create among the nations of the earth. See the notes at Psalm 2:2. An ample fulfillment of this occurred in the opposition to him when he came in the flesh, and in the resistance everywhere made since his death to his reign upon the earth. Nothing has produced more agitation in the world (compare Acts 17:6), and nothing still excites more determined resistance.
