isaiah 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, to take away our reproach. - Free Bible Online

      Isa 4:1-6.

      that day--the calamitous period described in previous chapter.
      seven--indefinite number among the Jews. So many men would be slain, that there would be very many more women than men; for example, seven women, contrary to their natural bashfulness, would sue to (equivalent to "take hold of," Isa 3:6) one man to marry them.
      eat . . . own bread--foregoing the privileges, which the law (Ex 21:10) gives to wives, when a man has more than one.
      reproach--of being unwedded and childless; especially felt among the Jews, who were looking for "the seed of the woman," Jesus Christ, described in Isa 4:2; Isa 54:1, 4; Lu 1:25.
