'Work' in the Bible

And on the seventh day God finished his work which he had made; and he rested on the seventh day from all his work which he had made.

And God blessed the seventh day, and hallowed it; because that in it he rested from all his work which God had created and made.

and he called his name Noah, saying, This same shall comfort us in our work and in the toil of our hands, which cometh because of the ground which Jehovah hath cursed.

And it came to pass about this time, that he went into the house to do his work; and there was none of the men of the house there within.
