Midras Mazmur 86:11: Shemot Rabbah & Midrash Tehillim

Another interpretation: “This is the statute of the paschal offering” – that is what Scripture states: “Let my heart be whole in Your statutes” (Psalms 119:80). David said: ‘Master of the universe, when I engage in Your statutes, let the evil inclination not have permission to look at me, as it is stated: “Teach me, Lord, Your way, I will walk in Your truth” (Psalms 86:11). [Do this] so that the evil inclination will not mislead me, and I will be ashamed before the righteous. Moreover, because it misleads me, I neglect the words of the Torah, and when I come to exhibit my learning before You and those who are lesser than I, they respond and say to me that it is not so, and I am ashamed. Rather, make my heart one, so it will engage in Torah wholely.’ That is what is written: “Let my heart be whole in Your statutes, so that I will not be put to shame” (Psalms 119:80).
Another interpretation: “Let my heart be whole in Your statutes” – these are the statute of the paschal offering, and the statute of the red heifer. Why? It is because they are similar to one another. About this [the paschal offering] it is stated: “This is the statute of the paschal offering,” about that [the red heifer] it is stated: “This is the statute of the Torah” (Numbers 19:2),⁴This passage recounts the laws of the red heifer, whose ashes are used to purify a person from ritual impurity imparted by contact with a dead body. and you cannot know which statute is greater than the other. It is analogous to two similar noblewomen who were walking together and looked the same. Which of them is greater than the other? It is the one who is accompanied by the other to her home, and the other walks behind her. So, regarding the paschal offering “statute” is stated and regarding the [red] heifer “statute” is stated. Which is greater? It is the heifer, as those who partake of the paschal offering need it, as it is stated: “They shall take for the impure from the ashes of the burning of the purification” (Numbers 19:17). That is: “No foreigner shall eat of it.”⁵The midrash understands the foreigner to be a person who is ritually impure.

My Lord, guide me in Your path. As David said before the Almighty, "If You see me deviating from Your path, it is for You that I do so." Guide me in Your path, my Lord. Rabbi Yitzhak said in the name of Rabbi Chanina bar Abba, "What is this matter similar to? It is like a person who had two cows, one that plowed and one that did not. What did he do? He removed the yoke from the plow and placed it on the other cow and made the one that did not plow, plow. What is something that does not desire to accept the burden that is placed upon it? It is forced to accept the burden against its will and is guided to where it is desired. So too, with the evil inclination, one must not guide it to where it desires to go, as it says, "Guide me in Your path, Lord." I will thank You, Lord, with all my heart, both with the good inclination and with the evil inclination, that I may not be ensnared by them. Rabbi Chiya asked, "What is 'And You saved my soul from the lowest depths?'" Rabbi Yudan said, "The path of adulterers is set in the depths of Sheol." Guide me, for Your kindness is great upon me, and You have saved my soul from the depths of Sheol....
