'Hard' in the Bible

And they said, Back there! And they said again, This one came to sojourn, and he must be a judge? Now we will deal worse with thee than with them. And they pressed hard on the man on Lot; and drew near to break the door.

And they journeyed from Bethel. And there was yet a certain distance to come to Ephrath, when Rachel travailed in childbirth; and it went hard with her in her childbearing.

And it came to pass when it went hard with her in her childbearing, that the midwife said to her, Fear not; for this also is a son for thee.
