Who will understand mistakes? Give me Rabbi Shimon ben Yochai, who the righteous are that know how to entice their Creator and know how to rebuke. See how David rebuked his Creator, he started by rebuking the heavens, as it says "The heavens tell of the glory of God." They replied, "Do you need anything?"
"No," he said, "but the work of His hands proclaims the firmament." Then he began to rebuke with the Torah, as it says "The fear of the Lord is pure." God said to him, "David, what do you want?" He replied, "Who will understand mistakes?
Your servant has committed many sins." God said to him, "I forgive you, and leave your sins." Even willful sins, which are the worst kind. They shall not rule over me.
These are sins of passion. As it is said, "Let not those who are wrongfully my enemies rejoice over me." This is the sin of the great transgression. Rabbi Levi said that David said to God, "Master of the Universe, You are a great God, and I owe a great debt to You.
Help me pay my debts." As it is said, "For Your Name's sake, O Lord, pardon my guilt, for it is great." Rav Acha the Kutite said of these sinners, that they know how to go around doors. At first, they say, "Give the poor man a little water."
When they change their mind, they say, "Give him one onion," and they give it to him. Then they say, "Give him an onion without bread," and they give it to him. The righteous also know how to please their Creator, as it says, "The lips of the righteous know what is pleasing." This refers to Moses.
But the wicked have twisted lips, because they do not know how to please God. Another interpretation is that the lips of the righteous know what is pleasing, referring to Moses. When he sought to bless Reuben, what did he say first? "The Lord came from Sinai." "He loves the peoples." "The Torah that Moses commanded us." "May Reuben live and not die."
