Musar su Salmi 136:2

Come see what is written in the Zohar (Parashas Balak, 200b- 202b): Rabbi Pinchas went to visit his daughter, the mother of Rabbi Elazar, who was ill. He was riding upon a donkey, accompanied by his companions. Along the way they came upon two Arabs. He inquired of them, “Has any voice ever been heard coming from this field?” They said, “We do not know about ‘ever,’ but we do know about our own time. One time some highwaymen passed through this field and spied a group of Jews. They were intent on robbing them when the sound of this donkey was heard coming from the field. It brayed twice and then a flame came and consumed them, saving the lives of those Jews.” “O Arabs!” Rabbi Pinchas exclaimed, “In the merit of what you have related to me you shall be saved from other bandits who are lying in wait for you!” Then Rabbi Pinchas wept, exclaiming, “Master of the Universe! You performed this miracle to save those Jews in my merit and I was not even aware of it!” He then recited the verse, “To the One who performs great wonders alone, for His lovingkindness is forever!” (Tehillim 136:2). “How many good things does the Holy One Blessed is He do for people, yet no one knows of them other than Him alone! A person is traveling along the road and bandits are lying in wait to kill him. Then along comes another person who has been sent to serve as ‘redemption money’ so that he may be spared. Yet he is not even aware of the goodness that the Holy One Blessed is He has performed for him. Only the Holy One Blessed is He alone knows. “This is the meaning of the verse, ‘To the One who performs great wonders alone, for His lovingkindness is forever!’ ”
