Ambrose of Milan, on Ps 110:10

“The fear of the Lord is the beginning of wisdom. A good understanding to all that do it: his praise continueth for ever and ever.”

“I think I shall not seem to be taking too much on myself, if, in the midst of my children, I yield to my desire to teach, seeing that the master of humility himself has said, "Come, you children, listen to me: I will teach you the fear of the Lord." Therein one may observe both the humility and the grace of his reverence for God. For in saying "the fear of the Lord," which seems to be common to all, he has described the chief mark of reverence for God. As, however, fear itself is the beginning of wisdom and the source of blessedness—for they that fear the Lord are blessed—he has plainly marked himself out as the teacher for instruction in wisdom and the guide to the attainment of blessedness.”
