'Grandson' in the Bible

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.

Then the men of Israel said to Gideon, "Rule over us, you and your son and your grandson also; for you have delivered us out of the hand of Mid'ian."

He hath neither son nor grandson among his people, nor any remaining in the places of his sojourn.
