מדרש על פסחים 4:12

Aaron argued with himself, saying: If I say to Israel, Give ye to me gold and silver, they will bring it immediately; but behold I will say to them, Give ye to me the earrings of your wives, and of your sons, and forthwith the matter will fail, as it is said, "And Aaron said to them, Break off the golden rings" (Ex. 32:2). The women heard (this), but they were unwilling to give their earrings to their husbands; but they said to them: Ye desire to make a graven image and a molten image without any power in it to deliver. The Holy One, blessed be He, gave the women their reward in this world and in the world to come. What reward did He give them in this world? That they should observe the New Moons more stringently than the men, and what reward will He give them in the world to come? They are destined to be renewed like the New Moons, as it is said, "Who satisfieth thy years with good things; so that thy youth is renewed like the eagle" (Ps. 103:5).
