'Grandson' in the Bible

Terah took his son Abram, his grandson Lot (Haran’s son), and his daughter-in-law Sarai, his son Abram’s wife, and they set out together from Ur of the Chaldeans to go to the land of Canaan. But when they came to Haran, they settled there.

And now swear to me here by God that thou wilt not deal deceitfully with me, nor with my son, nor with my grandson. According to the kindness that I have done to thee, thou shalt do to me, and to the land in which thou sojournest.

So he said to them, "Do you know Laban, the grandson of Nahor?" "We know him," they said.
