Psalms 119:36 - Joseph Benson’s Commentary on the Old and New Testaments

Incline my heart, &c. As the wisdom of man may conceive, and his tongue utter, great things of God and holiness, while his heart is averse from both; therefore David saith, not only, Give me understanding, but, incline my heart unto thy testimonies To the love and practice of them; and not to covetousness He mentions this in particular, because it is most opposite to God's testimonies, and does most commonly hinder men from receiving his word, and from profiting by it; and because it is most pernicious, as being the root of all evil.
