Let Israel say, "It is not becoming for a person to say that he is good about himself, unless others testify to his goodness." And who testifies to the goodness of the Lord? Jacob said, "The kindness you have shown me is not for a day or a year, but for eternity," as it is written, "I am unworthy of all the kindness and faithfulness you have shown your servant" (Genesis 32:11). They asked him, "How many kindnesses has He done for you?"
He replied, "They have no measure," as it is written, "God has shepherded me" (Genesis 48:15). Let Israel say, "What did I do to them in Egypt? And what did I pay them in the desert?" (Exodus 13:8) "And the Lord goes before them by day." (Exodus 13:21) "And what did they do to me at Sinai?" (Exodus 24:7) "All that the Lord has spoken, we will do and obey." At that moment, it was said, "I remember the kindness of your youth." (Jeremiah 2:2) Let Israel say, "Let the house of Aaron say, 'God is good, for His kindness is eternal.'"
This can be compared to a homeowner who treated his workers well, but at the time of accounting, he did not scrutinize their work. At the time of threshing, he would serve them the best wine, but they did not know what was going on behind the scenes. Who knows his servants and his palace attendants? And who are the servants of the Lord? The sons of Aaron, who offer sacrifices to Him at all times.
