Midrash su Giosuè 23:1

And Abraham was old, well stricken in age (Gen. 24:1). R. Joshua the son of Nahmani said: Men become old prematurely because of four things: fear, grief caused by children, a wicked wife, and wars. We learn about fear from David, as it is written: But David would not go before it to inquire of God; for he was terrified because of the sword of the angel of the Lord (I Chron. 21:30), and that is followed by the verse: And David was old (ibid., v. 31). The consequences of grief brought on by children we learn from Eli. It is written: Now Eli was very old; and he heard all that his sons did to all Israel (I Sam. 2:21). The effect of wars is recorded in what happened to Joshua after he fought with the thirty-one kings: And Joshua was old, well stricken with years (Josh. 23:1). We read about what transpires because of a wicked wife, in the verse: It came to pass, when Solomon was old, that his wives turned away his heart after other gods (I Kings 11:4). However, Abraham’s wife honored him and called him my lord, as is said: And my lord is old (Gen. 18:12). Concerning her Scripture states: A Virtuous woman is a crown to her husband (Prov. 12:4). Hence, it is written of him: And the Lord had blessed Abraham in all things (Gen. 24:1).
