Proverbs 23:12

Apply thine heart unto instruction
To the instruction of parents, and to the instruction of ministers of the word; to the Scriptures, which are profitable to instruction in righteousness; to the instruction of wisdom, or to the Gospel of Christ, which instructs in things relating to him, and to salvation by him: or, "bring in thine heart to instruction" ^F25; not only bring thy body to the place of instruction, the house of God, but bring thine heart thither also; and thine ears to the words of knowledge;
the doctrines of the Gospel, which are the means of the knowledge of God and Christ, and of all divine, spiritual, and heavenly tidings; and of a growth in the knowledge of them; and therefore should be diligently hearkened and cordially attended to.
