'Join' 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.

Absalom had gone to the king to ask him, "I've brought some men to shear the sheep. Won't you please come and join me, along with your senior staff?"
