I have more understanding than all my teachers: for thy testimonies [are] my meditation.
Ver. 99. I have more understanding than all my teachers] i.e. I have understood by much reading more than they ever taught me, while I referred all to practice; and so came to know more of God's mind than they did. A friend, saith Chrysostom, that is acquainted with his friend, will get out the meaning of a letter or phrase which another could not that is a stranger; so it is in the Scripture. And here, Indocti rapiunt coelum, a pious swain is better learned than a proud philosopher, saith a certain devout Dominican. Our King Alfred was held the best in all his kingdom, both for understanding and for interpreting the Holy Scriptures.
For thy testimonies are my meditation] I do particularly apply the word heard to mine own necessities; and work it upon mine affections by an after deliberate meditation.
