Rashi on Numbers 14:14/רש"י על במדבר י״ד:י״ד

1ואמרו אל יושב הארץ which is the same as על יושב הארץ THEY WILL SAY CONCERNING THE INHABITANTS OF THIS LAND — What will they say concerning them? That which is stated at the end of the paragraph, (v. 16):

2'מבלתי יכולת ה “Because the Lord was unable etc. … [he hath slaughtered them in the wilderness]”. — The connection between that verse and what preceeds is as follows: Because they have heard that Thou, O Lord, dwellest in their midst and that Thou appearest to them face to face and all this is in an affectionate manner (i.e. all this is evidence of the affection in which Thou holdest them), and until now they had not realized that Your love for them had been withdrawn.
