In parshat Toldot, we see a number of situations that occur to Yitzhak that are (almost) identical to those that occurred to his father, Avraham. Examples:
- There is a famine. Yitzchak seeks to go to Egypt, except that G-d tells him not to. (Genesis 26:1-6)
- When he goes to Gerar, he tells everyone that Rivka is his sister instead of his wife. Same excuse or for the same reasoning that Avrham said that when he went to Gerar. (Genesis 26:7)
- The people stuffed up the wells that Avraham dug, and they then stole the wells that Yitzhak dug himself. (Genesis 26:15-21)
- Avimelech makes a covenant with Yitzhak like he did with Avraham. (Genesis 26:26-31)
When Avimelech made the covenant with Avraham, he reproves Avimelech about the wells that he / his people stole. Yitzhak doesn't do as his father did. Why not?
