'Grandson' in the Bible

And Terah took Abram his son, and Lot, the son of Haran, {his grandson}, and Sarai his daughter-in-law, the wife of Abram his son, and went out with them from Ur of the Chaldeans to go to the land of Canaan. And they went to Haran, and they settled there.

And all the nations will serve him, and his son, and {his grandson}, until the coming of the time of {his own} land. Then many nations and great kings will let him work.
