“He stores up sound wisdom for the upright” (Prov. 2:7a). The phrase, “sound wisdom” (Heb. tushiya), means, “the effect of sound wisdom,” which is “abiding success.” (BDB) It means, “wisdom that leads to practical success.” (TWOT)
Hence, “if” you seek wisdom and ask for understanding, the Lord shall give you success. He will give you wisdom that will help you do your job. He will give you wisdom that will make you pass your exam. He will give you wisdom that you help you in your business. That is why the fear of the Lord brings you practical success. The fear of God shall make you succeed in life.
We see a parallelism between the two consequential clauses (apodosis) in vv. 5-8 and vv. 9-11.
A Then you will understand the fear of the Lord and find the knowledge of God. (v. 5)
B For the Lord gives wisdom; from his mouth come knowledge and understanding; (v. 6) he stores up sound wisdom for the upright (7a);
C he is a shield to those who walk in integrity, (v. 7b) guarding the paths of justice and watching over the way of his saints. (v. 8)
A1 Then you will understand righteousness and justice and equity, every good path; (v. 9)
B1 for wisdom will come into your heart, and knowledge will be pleasant to your soul; (v. 10)
C1 discretion will watch over you, understanding will guard you (v. 11)
Thus, we draw several conclusions based on this analysis. As A and A1 shows, to understand the fear of God is to understand righteousness, justice, and equality. In B and B1, as the Lord gives wisdom. Wisdom in turn comes into your heart. As C and C1 shows, the Lord guards the upright. Wisdom also guards their hearts and watches over them.
The fear of the Lord gives you His protection. He is a shield to you who walk in integrity. He guards you who walk in the paths of justice. He watches you who walk in piety and godliness. God will do this if you seek wisdom and follow it.
