“And shee being with childe, cried, trauailing in birth, and pained to be deliuered.”
1611 King James Version (KJV)
12:2 And being with child she crieth, travailing in birth - The very pain, without any outward opposition, would constrain a woman in travail to cry out. These cries, throes, and pains to be delivered, were the painful longings, the sighs, and prayers of the saints for the coming of the kingdom of God. The woman groaned and travailed in spirit, that Christ might appear, as the Shepherd and King of all nations.
Re 12:2 She being with child cried. Again we must let the Scripture explain its own meaning. "As soon as Zion travailed, she brought forth her children" (Isa 66:8). The travail of Zion causeth an increase. See also Isa 54:1 49:20, where the same figure is used. The state of the woman therefore implies a Church in sorrow, a suffering Church, but out of whose suffering there cometh an increase of the saints. It is a period when the saints are multiplied in the midst of persecution.
