Matthew Henry Presbyterian @wholebiblehenry

Here we have, I. A solemn preface, to introduce the caution which follows, Pro 5:1, Pro 5:2. Solomon here addresses himself to his son, that is, to all young men, as unto his children, whom he has an affection for and some influence upon. In God's name, he demands attention; for he writes by divine inspiration, and is a prophet, though he begins not with, Thus saith the Lord.

Commenting on Proverbs 5:1-14

John Gill Reformed Baptist @doctorgill

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.

regard--or, "observe." keep--preserve constantly.
