'Hard' in the Bible

After him Baruch, the son of Zabbai, was hard at work on another part, from the turning of the wall to the door of the house of Eliashib, the chief priest.

So we went on building the wall; and all the wall was joined together half-way up: for the people were working hard.

Now the food made ready for one day was one ox and six fat sheep, as well as fowls; and once in ten days a store of all sorts of wine: but all the same, I did not take the food to which the ruler had a right, because the people were crushed under a hard yoke.
