'Travailing' in the Bible

I have long time holden my peace; I have been still, and refrained myself: now will I cry out like a travailing woman; I will gasp and pant together.

The sorrows of a travailing woman shall come upon him: he is an unwise son; for it is time he should not tarry in the place of the breaking forth of children.

and she was with child; and she crieth out, travailing in birth, and in pain to be delivered.
