Proverbs 30:5

Every word of God is pure: he is a shield unto them that put their trust in him.
– Proverbs 30:5

Verses 5-6 form a wisdom saying about the trustworthiness of God’s word. This verse echoes a Davidic psalm line that was a part of David’s praise of Yahweh for fulfilling his word and delivering David from his enemies (2 Samuel 22:31). The line also appears in Psalms, such as Psalms 12:6 & 18:30.

The saying uses four terms that are frequent in the Psalms, sometimes all appearing together or in various combinations—word, pure, shield, and trust. Any combination of the terms, and especially a full combination, has strong covenantal implications. The word for word means an utterance, or anything spoken. It appears in all the references cited above. In all these uses, the term refers to the covenant promises of God. The word for pure is more often translated tried and literally means to smelt, refine, or test metal. The meaning is clear in uses such as Psalm 12:6 & Proverbs 25:4. The word for shield can refer to large or small shields, but is often used to speak of God’s encircling protection of those in covenant relationship with him (Psalm 3:3; Proverbs 2:7). The word for trust means to take refuge in and is a figure of the covenant relationship with God, being under his protection (Psalm 2:12; 5:11).

The saying means that God’s covenant promises are trustworthy because they have been tested and found free of any duplicity. Human covenants are often ambiguous and laced with loopholes, but it is not so with God’s covenants. Because his words are so reliable, he is a complete protection and refuge for those who trust in him. It’s worth noting that this verse and other similar verses, like the ones referenced above, are often used as prooftexts for Bible translations. However, none of these verses have anything to do with Bible translations

Proverbs 21:8

The way of man is froward and strange: but as for the pure, his work is right.
– Proverbs 21:8

The word for froward means crooked, or perverse. The word for strange means guilty. The first phrase means the guilty man goes in a crooked way. The same idea is expressed of the evil man in Proverbs 2:15. The word for pure means clean, or righteous. The word for right means straight, or upright. The contrast is obvious. The guilty walk a crooked way while the innocent walk a straight path. The purpose of the proverb is to teach wisdom and discernment. Wisdom here teaches a tree is known by its fruits.

Proverbs 20:9

Who can say, I have made my heart clean, I am pure from my sin?
– Proverbs 20:9

This proverb is a rhetorical question that anticipates a negative answer. Though “Most men will proclaim every one his own goodness” (Proverbs 20:6) and “All the ways of a man are clean in his own eyes” (Proverbs 16:2), wisdom teaches us God weighs the spirits and ponders the hearts of all. Wisdom concludes, “There is a generation that are pure in their own eyes, and yet is not washed from their filthiness” (Proverbs 30:12).

The word for heart means the inner being, including the mind, will, emotions, etc. The first phrase asks whose inner intentions and motivations are clean, or innocent. Being pure from my sin points to the outward acts being morally good, or upright. This proverb speaks of rich theological truth we refer to as the depravity of man. Man is a fallen and corrupt creature who cannot keep from sin, nor purify himself from its defilement (1 Kings 8:46; Proverbs 21:4; Job 9:30-31).

Proverbs 15:26

The thoughts of the wicked are an abomination to the LORD: but the words of the pure are pleasant words.
– Proverbs 15:26

The word for thoughts means contrivance, or plan. The plans, or imaginations, of the wicked are abominable to God (Proverbs 6:16-19; 24:9). The contrasted phrase, words of the pure, emphasizes God’s knowledge of the thoughts of men. Our hearts are ever open before him (Proverbs 15:11). The word for pure means clean and pleasant means agreeable, or delightful. The Lord hates a lying tongue but loves a tongue of truth (Proverbs 6:17; 12:22).
