These two verses go together, extending the message of verse 98. Here we see that David can exceed the knowledge and wisdom of his teachers. This verse is not said in a derogatory way to lessen the importance of David's teachers but rather to speak of teachers as teachers only, knowing that teachers can speak the law, not knowing of what they affirm (1 Tim. 1:7); but David seeks true wisdom and knowledge from God's testimonies, or the word of God, the Bible, since the word of God is superior to the knowledge of teachers where these teachers must resort for their wisdom and knowledge, also.
David's knowledge was greater than the ancients, those who lived many years before his day, because, as the word of God was revealed, it shed more and more light upon the character, purpose, and work of Jesus Christ, the Messiah, which David delineated in a great way in many of his psalms.
David kept God's precepts as superior to all of his teachers and of all the ancients who lived before him. Even so today we must keep his precepts and his testimonies; therefore, we can know "all things" (1 John 2:20), both carnal and spiritual, being led by the Holy Spirit through our faith in Jesus Christ.
