Thou hast seen all their vengeance and all their imaginations against me.

Wesley's Notes

3:60 Seen - Thou hast been a witness to all their fury.

Jamieson-Fausset-Brown Bible Commentary

60. imaginations-devices (Jer 11:19).

Their vengeance-means their malice. Jeremiah gives his conduct, when plotted against by his foes, as an example how the Jews should bring their wrongs at the hands of the Chaldeans before God.

Schin.

Matthew Henry's Concise Commentary

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.
