Midrash su Salmi 87:7

Rabbi Phineas said: On the eve of Sabbath the Israelites stood at Mount Sinai, arranged with the men apart and the women apart. The Holy One, blessed be He, said to Moses: Go, speak to the daughters of Israel, (asking them) whether they wish to receive the Torah. Why were the women asked (first)? Because the way of men is to follow the opinion of women, as it is said, "Thus shalt thou say to the house of Jacob" (Ex. 19:3); these are the women. "And tell the children of Israel" (ibid.); these are the men. They all replied (as) with one mouth, and they said: "All that the Lord hath spoken we will do, and be obedient" (Ex. 24:7). (The Scripture also says,) "They that sing as well as they that dance (shall say), All my fountains are in thee" (Ps. 87:7).
