John.16.21  When a woman is in travail she has sorrow, because her hour has come; but when she is delivered of the child, she no longer remembers the anguish, for joy that a child is born into the world.
Rom.8.22  We know that the whole creation has been groaning in travail together until now;
Gal.4.19  My little children, with whom I am again in travail until Christ be formed in you!
Gal.4.27  For it is written, "Rejoice, O barren one who does not bear; break forth and shout, you who are not in travail; for the children of the desolate one are many more than the children of her that is married."
1Thess.5.3  When people say, "There is peace and security," then sudden destruction will come upon them as travail comes upon a woman with child, and there will be no escape.
