As a pregnant woman about to give birth writhes and cries out in her pain, so were we in your presence, LORD. (NIV)
As a woman with child drawing near the time of her delivery is in pain and writhes and cries out in her pangs, so we have been before You (at Your presence), O Lord. (AMP)
Like as a woman with child, that draweth near the time of her delivery, is in pain, and crieth out in her pangs; so have we been in thy sight, O LORD. (KJV)
