Targum zu Dewarim 33:28

And Israel shall dwell safely as of old according to the benediction with which Jakob their father did bless them, for whose righteousness sake He will cause them to inherit the good land that yieldeth corn and wine; the heavens also above them will drop with the dews of blessing, and the rains of lovingkindness.

But Israel shall dwell safely by themselves according to the benediction with which Jakob did bless them, in the land yielding wine and oil, The heavens also above you are bidden to send down upon you the dew and the rain.
