English: “And Avraham prayed.” From where do we know that one who is asked by his fellow for forgiveness and does not forgive him is cruel? As it is said, “And Avraham prayed to God.”
On the daf / in context: Avraham’s willingness to pray (and thereby forgive) after the injury is the model for the duty not to withhold forgiveness when it is properly requested.
Type of Learning
Derash on the verse (Bavli sugya) — not a formal named middah of the 13. The act of intercession is taken as the paradigm of granting mechilah.
What Is Learned
One who refuses to grant forgiveness when properly asked is called cruel; Avraham’s prayer for Avimelech is the proof that forgiveness should be given.
