Reference for Yoma 45:2

ואיזו היא נטירה א"ל השאילני קרדומך אמר ליה לא למחר א"ל השאילני חלוקך אמר לו הילך איני כמותך שלא השאלתני זו היא נטירה

If one said to his fellow: 'Lend me your sickle', and he replied 'No', and to-morrow the second comes [to the first] and says: 'Lend me your axe'! and he replies: 'I will not lend it to you, just as you would not lend me your sickle' - that is revenge. And what is bearing a grudge? If one says to his fellow: 'Lend me your axe , he replies 'No', and on the morrow the second asks: 'Lend me your garment', and he answers: 'Here it is.
