(66) From under the heavens of the Lord.--The phrase is exceptional, but it is obviously equivalent to the whole world, considered as God's kingdom.

3:55-66 Faith comes off conqueror, for in these verses the prophet concludes with some comfort. Prayer is the breath of the new man, drawing in the air of mercy in petitions, and returning it in praises; it proves and maintains the spiritual life. He silenced their fears, and quieted their spirits. Thou saidst, Fear not. This was the language of God's grace, by the witness of his Spirit with their spirits. And what are all our sorrows, compared with those of the Redeemer? He will deliver his people from every trouble, and revive his church from every persecution. He will save believers with everlasting salvation, while his enemies perish with everlasting destruction.Persecute and destroy them in anger,.... As they have persecuted the people of God, do thou persecute them; and never leave pursuing them untie thou hast made a full end of them, as the effect of vindictive wrath and vengeance:

from under the heavens of the Lord; which are made by him, and in which he dwells; let them not have the benefit of them, nor so much as the sight of them; but let them perish from under them, Jeremiah 10:11.
