The Covenant of circumcision.
“And after he began to be ninety and nine years old, the Lord appeared to him: and said unto him: I am the Almighty God: walk before me, and be perfect.” (Genesis 17:1)
The wise man is a good man, possessing every virtue and the image of goodness.
“The words ‘be blameless’ are addressed to Abraham, to whom had been given the spirit of wisdom, holy, marvelously agile, unpolluted. The soul of the just man, therefore, must be in training night and day, ever on the lookout, never indulging in sleep but on perpetual watch, intent on God, so as to understand the things that are and to comprehend the causes of each. But wisdom is also the interpreter of future things: ‘She knows the things of old and infers the things to come. She understands turns of speech and the solutions of riddles. She has foreknowledge of signs and wonders and of the outcome of seasons and times.’ One who has obtained her, therefore, cannot but be good and perfect, because he possesses every virtue and is the very image of goodness. Even the sophists of this world drew from this text a definition of such a wise man: The wise man is (by definition) a good man and an accomplished communicator.” (4) St. Ambrose of Milan
