For I have known him, in order that he may command his children and his household after him to keep the way of Hashem by doing righteousness and justice, so that Hashem may bring upon Avraham that which He has spoken concerning him.
English: “Righteousness and justice.” Rabbi Simlai expounded: What is the meaning of the verse “He who walks in righteousness and speaks uprightly”? “He who walks in righteousness” refers to Avraham, as it is written of him, “For I have known him… to do righteousness and justice.”
On the daf / in context: In the list of those who fulfill the ideal of Yeshayahu 33:15, Avraham is identified as the archetype of “walking in righteousness” on the strength of this verse.
Type of Learning
Derash on the verse (Bavli sugya) — not a formal named middah of the 13. A later prophetic phrase is anchored in the description of Avraham.
What Is Learned
Avraham is the model of “one who walks in righteousness”; the Torah itself describes him as commanding his household to practice tzedakah and mishpat.
