'Work' in the Bible

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.

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

and he named him Noah, saying, "This same will comfort us in our work and in the toil of our hands, because of the ground which Yahweh has cursed."

About this time, he went into the house to do his work, and there were none of the men of the house inside.
