Luke 17:20

The coming of the internal kingdom explained to the Pharisees, Luke 17:20-21.

20. He was demanded of the Pharisees John the Baptist had opened his preaching with the proclamation of the kingdom of God at hand; Christ had done the same, and his apostles had followed their example. These Pharisees then desire Jesus to tell them when this kingdom shall arrive. Its phenomena should, before a great while, begin to show themselves.

Not with observation That is, of the firmamental phenomena. The eclipse of the moon would come to them by observation or watching. The new moon of the Passover was watched for by the Jews with much exactness. So the Jews expected that the Messiah’s kingdom would show its sign in the skies, and then the face of the world be changed and renewed. The dead would be raised; and a Messiah, all glorious and heroic, would lead the armies of Israel to the destruction of the foes of God. Hence, as prophecy seemed to point to that day as its era, doubtless there was much observation of the signs of the sky.
