Matthew Poole and continuators on Isaiah 66:14

14 And when you see this, your heart shall rejoice, and your bones shall flourish like an herb : and the hand of the Lord shall be known toward his servants , and his indignation toward his Enemies .

The peace, and tranquillity of the Church and the propagation of the Kingdom of Christ, is always the cause of an heart rejoycing to such as fear God, Psal. 105. 3. the reason is because it is the greatest object of their desires which are then satisfied, and their thoughts are then at rest, and besides they are members of the same body so as their own bones, which before are dry and withered, Eze. 37. 1, 2. and the sinews, and the flesh, comes again upon them, and the skin covers them above, so as they flourish like an herb in the spring, all whose verdure and beauty in the winter was concealed in the root hid in the earth.

And in this the power, protection, and influence of God for, of and upon such as truly serve and obey him, shall be made manifest and known.

But the wicked shall be under a quite contrary dispensation, Psal. 1. 4. As they have had a day which hath been to you the power of darkness: so you shall have a day, which shall be to them the power of darkness, as Gods hand shall be upon and toward such as fear me, to cover, and bless, and influence them, so his indignation shall in that day be shewed towards those of your nation who have declared themselves the enemies of the Lord.
