'Work' in the Bible

By the seventh day God completed His work which He had done, and He rested on the seventh day from all His work which He had done.

Then God blessed the seventh day and sanctified it, because in it He rested from all His work which God had created and made.

Now he called his name Noah, saying, “This one will give us rest from our work and from the toil of our hands arising from the ground which the Lord has cursed.”

Now it happened one day that he went into the house to do his work, and none of the men of the household was there inside.
