'Ancestors' in the Bible

""The LORD also announces to you: "The LORD will himself build a house for you. When your life is complete and you go to join your ancestors, I will raise up your offspring after you, who will come forth from your body, and I will fortify his kingdom.

But the woman from Tekoa told the king, "Your majesty, let any guilt for this be on me and on my ancestors' household, and not on my king or his throne!"
