I have more understanding than all my teachers,.... Such as had been or would have been his teachers, who were bad ones in religious matters; especially such might be the religious teachers in Saul's time, when David was a young man: as the priests, whose lips should keep knowledge, and deliver it to the people, were in the times of Malachi; and as the Scribes and Pharisees, who, sat in Moses's chair, were in Christ's time; and as those legal teachers were in the apostles' times, who would be teachers of the law, not knowing what they said, nor whereof they affirmed; such as these David exceeded in spiritual understanding.
Or his good teachers are meant; and though in common it is true that "a disciple is not above his master", Mt 10:24; yet there are sometimes instances in which scholars exceed their teachers in knowledge and learning; and this is no reproach to a master to have such scholars: no doubt Apollos so improved in knowledge as to excel Aquila and Priscilla, of whom he learned much; as the Apostle Paul excelled Ananias; and so David excelled his teachers: and which is said by him, not in an ostentatious way of himself, nor in contempt of his teachers; but to commend the word of God, the source of his knowledge; and to magnify the grace of God, to whom he attributes all his wisdom, as in Ps 119:98.
