O Unique and Unitary One, unify my heart to love and fear Your great, mighty and awesome Name with all my heart and soul.” Afterwards he should recite the eight verse beginning with the letter hei in Tehillim, Chapter 119 (verses 33-40). Then he should recite Mishlei 18:10, “The name of Hashem is a mighty tower, the righteous man runs into it and is protected.” And Tehillim 122:4: “The tribes of God, as a testimony for Israel to give thanks the Name of Hashem.” You recite eight verses of Tehillim 119 because they begin with the letter hei and end with the letter yud, spelling out the Name Y-h, which is the Name that served as testimony to the purity of the tribes of Israel in Egypt, as it is stated HaReuveiny (Bamidbar 26:7). [That is, when the families of Israel are listed in that passage a hei is appended to the beginning of each name and a yud to the end of each name, indicating that Hashem Himself attested to their purity].
