Rashi, on Isa 4:1

“And in that day seven women shall take hold of one man, saying: We will eat our own bread, and wear our own apparel: only let us be called by thy name, take away our reproach.”

“Now seven women shall take hold of one man because of the many widows. take away Heb. אסף [lit., gather in,] hide our reproach, similar to (Deut. 22:2): “And you shall gather it (ואספתו) into your house.” For the woman, when she is married, will not be dealt with licentiously. According to Midrash Aggadah, (Lamentations Rabbah 5:11) Nebuchadnezzar commanded (or decreed upon) [his armies] not to have relations with married women, lest they be punished. They, therefore, begged to be nominally married.”
