John Gill Commentary Isaiah 26:17

"Like as a woman with child, that draweth near the time of her delivery, is in pain and crieth out in her pangs; so we have been before thee, O Jehovah." — Isaiah 26:17 (ASV)

Like as a woman with child
By this simile are set forth the great distresses and afflictions the church of Christ will be in, before redemption and deliverance from the antichristian yoke comes: [that] draweth near the time of her delivery ;
when her burden is great and very troublesome: [is] in pain, [and] crieth out in her pangs ;
for her friends to come about her, and give her all the help and assistance they can: so have we been in thy sight, O Lord ;
in great distress and trouble, and crying to him for salvation and deliverance, all which were well known unto him.
