It is very interesting to note that, whether we study the Old Testament or the New, nights are always associated with God's mornings. In other words, he does not leave us in despair without sending to us his messengers of hope and cheer. The Prophet Isaiah in this particular part of his prophecy seems to be almost broken-hearted because of the sin of the people. As one of the Scotch preachers has put it, he has practically sobbed himself to sleep. A great shadow has fallen upon the people of God and he is in despair because of it. They have sown to the wind and now they are reaping the whirlwind, a result which is inevitable. They are away from Zion with its temple, and are deprived of the view of those mountains which are round about Jerusalem and to this day are clad with vines and olive trees. They are in captivity and are the abject slaves of the enemies of God. Isaiah's heart is well-nigh crushed, but in the midst of the despair he has a vision of the chariots coming and hears a cry which rejoices his soul, "Babylon is fallen." It is because of these tidings that he cries out in the words of the text. What a night they had had of it! They had been in darkness that was ever increasing, and the song of thanksgiving which used to fill their souls because of the nearness of Jehovah had entirely departed from them. The figure of the watchman is often used in the Bible, as for example when he stands upon the city walls and is told that if he sounds the trumpet telling of the approach of the enemy and the people hear and do not take warning their blood is upon their own heads, while if he fails to sound the trumpet and the people are cut off, their blood is required at the watchman's hand. And again in the first chapter of Zechariah the eighth to the eleventh verses, "I saw by night, and behold a man riding upon a red horse, and he stood among the myrtle trees that were in the bottom; and behind him were there red horses, speckled and white. Then said I, O my Lord, what are these? And the angel that talked with me said unto me, I will shew thee what these be. And the man that stood among the myrtle trees answered and said, These are they whom the Lord hath sent to walk to and fro through the earth. And they answered the angel of the Lord that stood among the myrtle trees, and said, We have walked to and fro through the earth, and behold all the earth sitteth still and is at rest." For here the man standing in the midst of the myrtle trees is him of whom the prophets did speak, while the messengers are those who bring him tidings of the progress of his kingdom. But again where David comes to the watch tower and sees the two messengers running, the second one bringing him tidings of the death of his son, and from this watch tower he staggers back again to his room crying out, "O Absalom, my son, would God I had died for thee!"
