Rashi, on Ps 26:8

“My heart hath said to thee: My face hath sought thee: thy face, O Lord, will I still seek.”

“On Your behalf, my heart says, “Seek My presence.” On Your behalf, as Your agent, my heart says to me, “All of you Israelites, seek My presence.” And I obey it. “Your presence, O Lord, I will seek.” [The word] לך is like (Job 33:6): “Behold I am like your mouth to God (לא-ל),” [that is,] in His stead; (ibid. 13:8), “Will you contend for God (לא-ל)?” [that is,] in His stead. Here, too, “On Your behalf, my heart says,” in Your stead, my heart comes to me to say this.”
