Matthew Poole and continuators on Jeremiah 50:7

7 All that found them have devoured them , and their adversaries said, We offend not, because they have sinned against the LORD , the habitation of justice , even the LORD, the hope of their fathers .

As they be in the condition of lost sheep, so they have been under the fate of lost sheep, which every Dog, Fox▪ Wolf devours.

And those that are their Enemies have pretended that in destroying them they have done no ill because they had sinned, so as the sins of the Iews did both expose them to the Wrath of God, and also emboldned their Enemies, and encouraged them to think that they did God Service in destroying them.

The habitation of Iustice. Some think this is a name here given to God, who indeed is the habitation of Justice, but whether the Chaldeans would call him so may be a question. Others therefore think the preposition in is understood, making this the aggravation of the Iews sins, that they were committed in a land which ought to have been an habitation of Justice, as Isa. 26.10. it is said that the wicked man in a land of uprightness will deal unjustly. Mr. Calvin hath another notion, viz. That the Prophet here incourageth himself against what the Adversaries had promised themselves because the people had offended God: viz. that notwithstanding this, God was a righteous God, in whom Justice dwelt, and who would be faithful to his Promises.

And he was their hope, and had been he in whom their Fathers before them had hoped, and that not in vain.
