ה֘וֹרֵ֤נִי יְהוָ֨ה ׀ דַּרְכֶּ֗ךָ אֲהַלֵּ֥ךְ בַּאֲמִתֶּ֑ךָ יַחֵ֥ד לְ֝בָבִ֗י לְיִרְאָ֥ה שְׁמֶֽךָ׃
Ajarlah aku, ya Yang Mahakekal, jalan-Mu, supaya aku berjalan dalam kebenaran-Mu; satukanlah hatiku untuk takut akan nama-Mu.

In the Midrash Rabbah on Exodus, parasha 19, it states, It is written: “Let my heart be undivided in your hukim [statutes] in order that I may not be put to shame.”57Psalms 119:80. David said: “Lord of the universe! When I occupy myself with Your statutes, let not the Tempter have power to influence me, as it says: ‘Teach me, God, Your way, that I may walk in Your truth; [unite my heart to revere Your Name].’”58Psalms 86:11.

ויקרא בהם שמי ושם אבותי אברהם ויצחק. Although we know that Avraham and Yitzchok were both Yaakov’s fathers, he meant to make plain that he did not appeal to the god of Terach or Nachor who were similarly his “fathers” in the sense of being his ancestors. It is an axiom throughout Scripture that the righteous are never linked to those of their ancestors who were wicked, i.e. idolaters. The same is true in reverse as our sages say in Sanhedrin 52, (but not found there) קרינן לרשיעא אפילו בר צדיקא רשיעא בר רשיעא, “a wicked person, even if he is the son of a righteous person is still called a wicked person son of a wicked person.” This principle is invoked in order to save the righteous father the embarrassment of being associated with his son who has turned from the path of righteousness. When the ancestry of such a wicked person requires to be mentioned, one prefers to link him to another wicked person in his lineage. This is why Yaakov prayed for the lads that they should remain G’d fearing and prepared to serve Him. If they were to do this they would qualify to be described as offspring of Avraham and Yitzchok. This principle is known as יחד לבבי ליראה את ה', “let my heart be undivided in reverence for Your name.” (Psalms 86,11)
