Midrash for Deuteronomy 1:24

(Devarim 1:24) "And they turned and they went up to the mountain": We are hereby apprised that it is the way of spies to go up a mountain. And thus Rachav said to the spies of Joshua (Joshua 2:16) "Go up the mountain lest the pursuers catch you." We are hereby taught (Ibid. "Conceal yourselves there for three days until the pursuers turn back") that the holy spirit reposed upon her, for if not, how could she know that they would turn back in three days?
