What are "Chormim"?
Radak citing Targum Yonasan: They tend vineyards.
Radak citing Shabbos 26a: They are people who pick Afarsemon from Ein Gedi.
What are "Yogvim"?
Rashi: They dig in the ground. This is related to Yekevim 1 , i.e. pits in the ground (to press wine).
Rashi (Yirmeyah 52:16), from Shabbos 26a: They are people who hunt the Chilazon 2 [Radak - from the ladders (steep inclines) of Tzur until Chaifa].
Radak citing Targum Yonasan: They are people who work in fields.
Ramban (Shemos 28:31): The letters Gimel and Kuf are sometimes interchanged (because they are articulated from the same place in the mouth - Harei Besamim 2 155.)
The corresponding verse in Yirmeyah 39:10 says that he gave to them vineyards and Yegevim. Rashi (26a) says that Yogvim is like Yekevim (refer to 25:12:2:1 and the note there), where they press the Chilazon to squeeze out its blood. (PF)
Why did he leave the poor people, and not exile them?
Malbim (Yirmeyah 39:10): He knew that they would not rebel against him, for he gave to them vineyards and fields 1 .
So it says there. Here and in Yirmeyah 52:16, it says that he left them to be Chormim and Yogevim (people who tend vineyards and fields). It does not say that he gave land to them. (PF)
