Yirmeyahu 31:1 So says Hashem: In the wilderness, the people who had escaped the sword found favor; He [therefore] went to give Yisrael their resting place.

Rashi on 31:1 FOUND FAVOR. The generation of the wilderness found favor in My eyes.

WHO HAD ESCAPED THE SWORD of the Egyptians the Amalekim and the Kenaanim.

HE [THEREFORE] WENT TO GIVE YISRAEL THEIR RESTING PLACE when He led them to take possession of the land of their rest.

31:2
