שבת לא,א

The Dubner Magid gives us another meaning on the expression מה דלך סאני לחברך לא תעבוד with a mashel. A young man took his uncle as a financial advisor. He would constantly tell him that he is losing money. Eventually, he had enough. He decided to go to someone else who told him to separate himself from his uncle because he is a ganev who realy is making money. The yetzer hara who has hatred towards you don’t make him your friend.

The two legs are mitzvos בין אדם לחבירו and בין אדם למקום. One with out the other does not go. The two explanations by Rashi whether your friend is Hashem or your friend is dependent which leg the convert wanted to stand on.
