Psalms 118:100

100. But these teachers may be understood very reasonably to be those aged men, of whom he presently saith, “I am wiser than mine elders” ( ver. 100 ). And this seemeth to me to be repeated here thus, that that age of His which is well known to us in the Gospel might be called to our remembrance; the age of boyhood, during which He was sitting among the aged, understanding more than all His teachers. For the smaller and the greater in age are wont to be termed younger and elder, although neither of them hath arrived at or approached old age; although if we are concerned to seek in the Gospel the express term, elders, more than whom He understood, we find it when the Scribes and Pharisees said unto Him, “Why do Thy disciples transgression the tradition of the elders? for they wash not their hands when they eat bread.” Behold the transgression of the tradition of the elders is objected to …

142. “Thy testimonies are righteousness unto everlasting: O grant me understanding, and I shall live” ( ver. 144 ). This younger one prayeth for understanding; which if he had not, he would not be “wiser than the aged;” but he prayeth for it in trouble and hardships, that he may thereby understand how contemptible is all that his persecuting enemies can take from him, by whom he saith he hath been despised. Therefore he hath said, “and I shall live:” because if trouble and heaviness reached such a pitch, that his life should be terminated by the hands of his persecuting enemies, he will live for ever, who preferreth to temporal things, righteousness which remaineth for evermore. This righteousness in trouble and hardship are the Martyria Dei, that is, the testimonies of God, for which Martyrs have been crowned.
