Do not unto others that which is hateful unto thee.
Golden Rule”: “That which is hateful to you, do not do to your fellow. That is the whole Torah; the rest is the explanation; go and learn.
If I am not for myself, then who will be for me? But when I am for myself, then what am "I"? And if not now, when?
The shy man will not learn; the impatient man should not teach.
If not you, who? If not now, when?
What you yourself hate, don't do to your neighbor. This is the whole law; the rest is commentary. Go and study.
