Rashi
The words of Jeremiah son of Hilkiah Let the son of the corrupt woman, whose deeds are proper Jeremiah was descended from Rahab the harlot and let him reprove the son of the righteous woman whose deeds are corrupt these are Israel who corrupted their deeds who are descended from legitimate seed.
Rashi
And from the hands of Shaul. Shaul was part of the general grouping [of "his enemies"]?1I.e. Why is he being singled out? but he was his greatest enemy and pursuer. Similarly [we find], "Nineteen men and Asohel2Earlier in 2:30. where Asohel is singled out because he was equal to all of them as Rashi points out there. Similarly, "Go spy out the land and Yericho."3Yehoshua 2:1. And similarly, "King Shlomo loved [many] foreign women and [he loved] the daughter of Pharoah."4Melochim I, 11:1.
Rashi
and from the hand of Saul Was not Saul included? But [he is mentioned specifically] because he was the harshest to him and pursued him more than all of them. Similarly, you say (in Josh. 2:1): “see the land and Jericho.”
