אַשְׂכִּֽילְךָ֨ ׀ וְֽאוֹרְךָ֗ בְּדֶֽרֶךְ־ז֥וּ תֵלֵ֑ךְ אִֽיעֲצָ֖ה עָלֶ֣יךָ עֵינִֽי׃
내가 너의 갈 길을 가르쳐 보이고 너를 주목하여 훈계하리로다
Rabbeinu Bahya
Seeing that man shares common features with the essence of vegetation as well as with the essence of the mobility of the animals, he had to be equipped with an abstract intelligence in order for him to represent a higher stage of development than the stages of physical phenomena which preceded him. Even though all these facts are something we observe daily with our own eyes, Scripture nonetheless confirmed these facts. This is why we read in Job 35,11: “who gives us more knowledge than the beasts of the earth, makes us wiser than the birds of the sky?” By means of this additional intellect man proceeds to examine both his physical dimension as well as his spiritual dimension. He evaluates their respective worth. When man succeeds in making his spirituality his dominating feature he is likened to מלאך ה' צבאות, “an angel of the Lord G’d of Hosts” (Malachi 2,7), whereas when he allows his physicality to dominate him, placing his intellect into the service of his body, he is compared to the beasts as we know from Psalms 49,21 נמשל כבהמות נדמו, “he is like the beasts that perish (have no afterlife).”
David is at pains to warn man not to allow this to happen when he says (Psalms 32,8) “Let me enlighten you and show you which way to go; let me offer you counsel; my eye is on you.” He warns man further not to follow his “nature,” i.e. physicality, saying in verse nine of the same psalm: “be not like a senseless horse or mule whose movement must be curbed by bit and bridle; far be it from you!”...

Chizkuni
ותורותי, “and My teachings;” this is a reference to the beginning of chapter 12 where G-d instructs Avraham to leave home and to proceed to a land that He will show him. As proof that this interpretation is correct, the author quotes Psalms 32,8: אשכילך ואורך בדרך זו, “Let me enlighten you and show you which way to go.” [The subject speaking in that verse is the Holy Spirit. (Alshich) He quotes a similar verse from Psalms 32,8.] Whenever the word תורה occurs, it refers to teaching [as a prelude to commanding the listener to conduct himself in accordance with it.] But the plain sense of the verse is that it refers to the 7 universal laws that apply to all of mankind.
Rashi
He winks his eyes Heb. עצה, an expression of winking, and so (Ps. 32:8): “I will wink (איעצה) to you my eye.”
