25:5 Everything he owned Abraham left to his son Isaac. 25:6 But while he was still alive, Abraham gave gifts to the sons of his concubines and sent them off to the east, away from his son Isaac.

25:7 Abraham lived a total of 175 years. 25:8 Then Abraham breathed his last and died at a good old age, an old man who had lived a full life. He joined his ancestors.
