'Grandson' in the Bible

Terah took Abram his son, and Lot the son of Haran, his grandson, and Sarai his daughter-in-law, his son Abram’s wife; and they went out together to go from Ur of the Chaldeans into the land of Canaan; but when they came to Haran [about five hundred and fifty miles northwest of Ur], they settled there.

So he said to them, “Do you know Laban the grandson of Nahor [Abraham’s brother]?” And they replied, “We know him.”
