Genesis 26:5

Because that Abraham obeyed my voice
In all things, and particularly in offering up his son at his command: and kept my charge;
whatever was given him in charge to observe; this, as Aben Ezra thinks, is the general, of which the particulars follow: my commandments, my statutes, and my laws;
whether moral, ceremonial, or civil and judicial; all and everyone which God enjoined him, he was careful to observe. Here seems to be something wanting, for the words are not to be joined with the preceding, as if Abraham's obedience was the cause of the above promises made to Isaac, or to himself: but this is mentioned rather as an example to Isaac, and to stir him up to do the like, as if it was said, because or seeing that Abraham thy father did so and so, do thou likewise.
