'Old Man' in the Bible

And Abraham will say to the old man of his house ruling over all which is to him, Put now thy hand under my thigh.

And he will ask them concerning peace, and he will say, Is it peace to your father, the old man of whom ye spake? Is he yet living?

And we said to my lord, There is a father to us, an old man, and a child of old age, a little one: and his brother died, and he will be left alone to his mother; and his father loved him.
