יְהוָ֤ה ׀ נְחֵ֬נִי בְצִדְקָתֶ֗ךָ לְמַ֥עַן שׁוֹרְרָ֑י הושר [הַיְשַׁ֖ר] לְפָנַ֣י דַּרְכֶּֽךָ׃
永恆者啊，求你因那些窺伺我的仇敵，憑著你的公義引導我；求你使你的道路在我面前平直。
Rashi
those who lie in wait for me Heb. שוררי, those who look after me, who look forward to my betraying You, so that You should forsake me. [The word] שוררי is like (Num. 24:17): “I behold it (אשורינו), but it is not near.”
Ibn Ezra
Ad-nai [lead me] (ה' - Ad-nai): The beginning/essence of my prayer (techilat tefilati) is that You lead me (she-tancheni) in the way of Your righteousness (be-derekh tzidkatekha).
Radak
Lead me, O Lord, in Thy righteousness: – This is my prayer unto Thee, that Thou shouldest lead me in Thy righteousness, meaning that Thou shouldest help me to go in the way of righteousness and justice, and lead me in it so that I may not stumble.
