מדרש אויף שמות 19:2

(Ibid. 2) "And they journeyed from Refidim and they came to the desert of Sinai": Is it not already written (Ibid. 1) "they came to the desert of Sinai"? — Their journeying from Refidim is being likened to their coming to the desert of Sinai. Just as the latter was in a state of repentance, so, the former.

(Exodus 19:2) "And Israel encamped there": Elsewhere it is written "and they journeyed," "and they encamped" — they journeyed in quarrel and encamped in quarrel. Here, they were of one heart — wherefore it is written "and (it) encamped." "and Israel encamped there": He said to them, you will be there for a (relatively) long time. And, indeed, we find that they were there for twelve months less ten days. "opposite the mountain": to the east of the mountain. "opposite" always signifies to the east.

[(Exod. 19:1:) ON THE THIRD NEW MOON.] This text is related (to Prov. 3:17): <WISDOM'S> WAYS ARE WAYS OF PLEASANTNESS, <AND ALL HER PATHS ARE PEACE.>²⁷PRK 12:14. The Holy One wanted to give Torah to Israel at the time that Israel came forth from Egypt, but they were disagreeing with each other and were always saying (in Numb. 14:4): LET US APPOINT A LEADER AND RETURN TO EGYPT. What is written (in Exod. 13:20)? THEY JOURNEYED FROM SUCCOTH AND ENCAMPED AT ETHAM, because they were journeying in dissension and camping in dissension. When they came to Rephidim, they all became harmonious and formed a single group. And where is it shown that they all formed a single group? Where it is stated (in Exod. 19:2): AND ISRAEL ENCAMPED THERE BEFORE THE MOUNTAIN. The plural form of "encamped" is not written here but "encamped" in the singular.²⁸In Exod. 13:20 Israel was treated as a plural noun and placed with a plural verb because it represented a nation of individuals, but here a united Israel is seen as a noun in the singular. The Holy One said: All of the Torah is peace. So to whom shall I give it? To a people that loves peace. Ergo (in Prov. 3:17): <WISDOM'S WAYS ARE WAYS OF PLEASANTNESS, > AND ALL HER PATHS ARE PEACE.
