He layeth up sound wisdom for the righteous: he is a buckler to them that walk uprightly.
The only God has blessings for your obedience – wisdom and protection. He provides true and valid wisdom in abundance for righteous men. God has all the wisdom in the universe, but He has made much available for good men. And He will also be a buckler to them as well, which shows strong protection by using the metaphor of a battle shield.
As in any writing, check the context to grasp this proverb. King Solomon, the Preacher of Israel, had listed the means for finding the fear of the Lord and the knowledge of God (Pr 2:1-5). He then taught that since God is the fountain and source of wisdom, knowledge, and understanding, He gives these things abundantly to faithful men or women (Pr 2:6-9).
Reader, what will you do? Here are wisdom and protection for life. They are available to all who will humble themselves and seek them from the LORD Jehovah, beside Whom there is no other god. When a man chooses to follow the way of righteousness revealed in the Bible, God will reveal truth and wisdom to Him (Ps 119:100; John 7:17).
If you follow the world – the way of folly and sin, you will suffer the dire consequences of being blinded horribly (Rom 1:18-27), of having God turn against you (Pr 1:20-32; Is 63:10), and dying a miserable death in ignorance and sorrow (Pr 5:11-13; 8:36). But you can also choose life and blessing, which God will give for obedience (I Pet 3:10-12).
How much wisdom has God laid up for the righteous? The Bible contains more wisdom than all the educators and institutions of “higher learning” combined (Is 8:20; I Cor 1:19-20; I Tim 6:20). On any subject, the Bible provides answers that confound and shame the ignorance of men (Ps 94:11; 119:113,128). How much time do you spend reading it?
God appointed Solomon Preacher in Israel to give inspired wisdom to His people (Eccl 1:1,12; 12:8-11). And He has ordained more preachers through Jesus Christ since His resurrection and ascension into heaven (Ps 68:18; Eph 4:8-16). It is your privilege to seek them out and find your wisdom from God (Jer 3:15; Mal 2:7; Col 1:28; II Tim 3:16-17).
What is a buckler? It is a shield (I Chr 5:18; Song 4:4). When listed with a shield, it is different in size, construction, or battle use (Ps 35:2). By using buckler as a metaphor, Solomon taught God’s protection for upright men (Pr 30:5; Ps 18:2,30; 84:11; 144:2). The angels of Jehovah, spirit beings superior to men by any measure, are servants for those who fear God and keep His commandments (Ps 34:7; Heb 1:13-14). “I will both lay me down in peace, and sleep: for thou, LORD, only makest me dwell in safety” (Ps 4:8).
The maximum safety you can have on earth is to walk uprightly, which is to have goals, habits, and a lifestyle of doing what is right. The eyes of Almighty God look throughout the world to show Himself strong for those with perfect hearts (II Chr 16:9). Not only will God protect the godly man during life on earth, righteous living is also the assurance and evidence that you will be safe in the Day of Judgment (Matt 7:21-23; II Pet 1:5-11).
