the fear, &c. That is only "the beginning of wisdom", not the end. See note on Proverbs 1:7 .

He layeth up sound wisdom for the righteous: he is a buckler to them that walk uprightly.

Compare Job 5:12 (enterprise = anything stable); Proverbs 6:13 (wisdom = stability); Proverbs 11:6 ; Proverbs 12:16 (wisdom = stability); Proverbs 26:3 ; Proverbs 30:22 (substance). Proverbs 2:7 ; Proverbs 3:21 ; Proverbs 8:14 (sound wisdom); Proverbs 18:1 (wisdom = all that is). Isaiah 28:29 (workings everything that is).

Then shalt thou understand righteousness, and judgment, and equity; yea, every good path.

Then, &c. Another conclusion, as in Proverbs 2:2 and Proverbs 2:5 .

10.

When wisdom entereth into thine heart, and knowledge is pleasant unto thy soul;

When, &c.: or because. Commencing the particular instructions as to the practical power of wisdom, to keep from evil men (verses: Proverbs 2:10-15 ) and the foreign woman (verses: 16-19); and in the way of good men (verses: Proverbs 2:20-22 ). See App-74 .
thy soul = thee. Hebrew. nephesh. App-13 .

strange woman. Hebrew. zur = apostate to a false religion, of which prostitution formed part.
stranger = foreigner. Hebrew. nakar = foreign woman. Not of Abraham's seed (Genesis 17:12 ): ever a snare to Israel.

17.

Which forsaketh the guide of her youth, and forgetteth the covenant of her God.

18.

For her house inclineth unto death, and her paths unto the dead.

house. Put by Figure of speech Metonymy (of Adjunct), App-6 , for household.
the dead. Hebrew Rephaim, who have no resurrection. Compare Isaiah 26:14 ("deceased"), Isaiah 26:19 ("the dead"); and see App-25 . This shows that a Canaanite woman is referred to here.

19.

None that go unto her return again, neither take they hold of the paths of life.
