'Toil' in the Bible

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 Joseph called the name of the first-born Manasseh: For,'said he , God hath made me forget all my toil, and all my father's house.
