That thou mayest regard discretion
Observe it; retain it in thine heart, as Aben Ezra adds, and use
it; think, speak, and act discreetly, and so avoid the bad woman
afterwards described: the Vulgate Latin version is, "that thou
mayest keep the thoughts"; and so Gersom interprets the word;
"good thoughts", according to the Septuagint version; the
thoughts of the heart are to be observed. A man of spiritual
wisdom will take notice of them; evil thoughts, which lead to
uncleanness, are to be repressed and kept in; good ones to be
cherished and improved; wise and sagacious ones (such the word
here used signifies) are to be attended to, as being of great
advantage in the various affairs and business of life; and
spiritual and evangelical wisdom helps to such thoughts, and
directs to the observance and exercise of them; and [that]
thy lips may keep knowledge;
may be able to speak of things worthy to be known, and
communicate the knowledge of them to others; by which means
useful knowledge will be kept and preserved, and be continued in
successive ages; see ( Malachi 2:7 ) ; even
the knowledge of God and of Christ, and of the Gospel and its
doctrines; and which will be a means of preserving men, as from
false doctrine, error, and heresy, so from profaneness and
immorality; and particularly from the adulterous woman, next
described.
