Midrash for Numbers 34:18

Another matter, “my beloved spoke up [ana], and he said [ve’amar] to me” (Song of Songs 2:10). Rabbi Azarya said: Is speaking not the same as saying? Rather, he answered [ana] me by means of Moses and said to me by means of Aaron. What did He say to me? Rise, my love, my fair one.” “For, behold, the winter is past” (Song of Songs 2:11), these are the forty years that Israel spent in the wilderness. “The rain is over and gone” (Song of Songs 2:11), these are the thirty-eight years during which it was as though the Israelites were ostracized in the wilderness, and the divine speech did not communicate with Moses until that entire generation was gone. That is what is written: “The days that we went from Kadesh Barnea…[were thirty-eight years]…the hand of the Lord was against them…it was when [the death of all the men of war] was concluded (Deuteronomy 2:14–16). Immediately, “the Lord spoke to me saying” (Deuteronomy 2:17).
“The blossoms [hanitzanim] have appeared in the land” (Song of Songs 2:12), the administrators [hanatzoḥot] have appeared in the land; these are the princes, as it is stated: “And one prince from each [tribe]” (Numbers 34:18). “The time of the nightingale [hazamir] has arrived” (Song of Songs 2:12), the time for the foreskin to be cut off [shetizamer] has arrived, the time for the Canaanites to be cut off has arrived, the time for the Land of Israel to be divided among Israel has arrived, as it is stated: “To these, the Land shall be divided” (Numbers 26:53). “The sound of the turtledove [hator] is heard in our land” (Song of Songs 2:12), Rabbi Yoḥanan said: The voice of a good explorer [tayar] was heard in our land; this is the voice of Joshua, at the time that he said: “Pass through the midst of the camp” (Joshua 1:11). “The fig tree has formed its unripe figs” (Song of Songs 2:13), these are the baskets of first fruits. “The vines in blossom have emitted fragrance” (Song of Songs 2:13), these are the libations.
