'Hard' in the Bible

and they embittered their life with hard labour in clay and bricks, and in all manner of labour in the field: all their labour with which they made them serve was with harshness.

And Moses spoke thus to the children of Israel; but they did not listen to Moses from anguish of spirit, and from hard service.

And they judged the people at all times: the hard matters they brought to Moses, but every small matter they judged.
