Charles Ellicott Commentary Psalms 119:99

"I have more understanding than all my teachers; For thy testimonies are my meditation." — Psalms 119:99 (ASV)

More understanding ... —The Rabbinical writers disliked the idea of a scholar professing wisdom above his teachers, and rendered, “from all my teachers I got wisdom,” which was certainly far more in keeping with the process by which the Talmud grew into existence.
