IV. What is the nature of this sword, and what are the intentions and limitations of it as to the people of God, v. 13. It is a correction; it is designed to be so; the sword to others is a rod to them. This is a comfortable word which comes in in the midst of these terrible ones, though it be expressed somewhat obscurely. 1. The people of God begin to be afraid that the sword will contemn even the rod, that the sword will go on with such fury that it will despise its commission to be a rod only, will forget its bounds and become a sword indeed, even to God's own people. They fear lest the Chaldeans' sword, which is the rod of God's anger, contemn its being called a rod, and become as the axe that boasts itself against him that heweth therewith or the staff that lifts up itself as if it were no wood, Isa. x. 15. Or, "What if the sword contemn even the rod? that is, what if this sword make the former rods, as that or Sennacherib, to be contemned as nothing to this? What if this should prove not a correcting rod, but a destroying sword, to make a full end of our church and nation?" This is that which the thinking, but timorous, few are apprehensive of. Note, When threatening judgments are abroad it is good to suppose the worst that may be the consequences of them, that we may provide accordingly. What if the sword contemn the tribe or sceptre? namely, that of Judah and the house of David (so some think Shebet here signifies); what if it should aim at the ruin of our government? If it do, the Lord is righteous and will be gracious notwithstanding. But, 2. These fears are silenced with an assurance that it is not so; the sword shall not forget itself, nor the errand on which it is sent: It is a trial, and it is no more than a trial. He that sends it makes what use of it, and sets what bounds to it, he pleases. Here shall its proud waves be stayed. Note, It is matter of comfort to the people of God, when his judgments are abroad, and they are ready to tremble for fear of them, that, whatever they are to others, to them they are but trials; and, when they are tried, they shall come forth as gold, and the proving of their faith shall be the improving of it.
