II. Upon what considerations God would give Nebuchadnezzar this success against Egypt; it was to be a recompence to him for the hard service with which he had caused his army to serve against Tyre, v. 18, 20. 1. The taking of Tyre was a tedious piece of work; it cost Nebuchadnezzar abundance of blood and treasure. It held out thirteen years; all that time the Chaldean army was hard at it, to make themselves masters of it. A large current of the sea, between Tyre and the continent, was filled up with earth, and many other difficulties which were thought insuperable they had to struggle with; but so great a prince, having begun such an undertaking, thought himself bound in honour to push it on, whatever it cost him. How many thousand lives have been sacrificed to such points of honour as this as! In prosecuting this siege every head was made bald, and every shoulder peeled, with carrying burdens and labouring in the water when they had a strong tide and a strong town to contend with. Egypt, a large kingdom, being divided within itself, is easily conquered; Tyre, a single city, being unanimous, is with difficulty subdued. Those that have much to do in the world find some affairs go on a great deal more readily and easily than others. But, 2. In this service God own that they wrought for him, v. 20. He set them at work, for the humbling of a proud city and its king, though they meant not so, neither did their heart think so, who were employed in it. Note, Even great men and bad men are tools that God makes use of, and are working for him even when they are pursuing their own covetous and ambitious designs; so wonderfully does God overrule all to his own glory. Yet, 3. For this service he had no wages nor his army. He was at a vast expense to take Tyre; and when he had it, though it was a very rich city, and he promised himself good plunder for his army from it, he was disappointed; the Tyrians sent away by ship their best effects, and threw the rest into the sea, so that they had nothing but bare walls. Thus are the children of this world ordinarily frustrated in their highest expectations from it. Therefore, 4. He shall have the spoil of Egypt to recompense him for his service against Tyre. Note, God will be behind-hand with none for any service they do for him, but, one way or other, will recompense them for it; none shall kindle a fire on his altar for nought. The service done for him by worldly men, with worldly designs, shall be recompensed with a mere worldly reward, which his faithful servants, that have a sincere regard to his will and glory, would not be put off with. This accounts for the prosperity of wicked men in this world; God is in it paying them for some service or other, in which he has made use of them. Verily they have their reward. Let none envy it them. The conquest of Egypt is spoken of as Nebuchadnezzar's full reward, for that completed his dominion over the then known world in a manner; that was the last of the kingdoms he subdued; when he was master of that he became the head of gold.
