Charles H. Spurgeon on Psalms 111:10

Beginning of wisdom. The word translated beginning is of uncertain sense. It may signify the first in time only, and so the rudiments, first foundation, or groundwork, and so though the most necessary, yet the most imperfect part of the work. And if it should thus be understood here and in other places, the sense would be no more but this, that there were no true wisdom, which had not its foundation in piety and fear of God. But the word signifies the first in dignity as well as in order or time, and is frequently used for the chief or principal of any kind...And thus it is to be understood here, that the fear of the Lord (which signifies all piety) is the principal or chief of wisdom, as sapientia prima in Horace is the principal or most excellent wisdom; according to that of Job 28:28: Unto man he said, Behold, the fear of the Lord, that is wisdom; and to depart from evil is understanding, that, by way of eminence, the most excellent wisdom and understanding. —Henry Hammond.
