Psalms 89:18

89:18 For our shield belongs to the Lord,

our king to the Holy One of Israel.

Proverbs 30:5

30:5 Every word of God is purified;

he is like a shield for those who take refuge in him.


tn The phrase “our shield” refers metaphorically to the Davidic king, who, as God’s vice-regent, was the human protector of the people. Note the parallelism with “our king" here and with “your anointed one” in Ps 84:9.

sn The basic sense of the word “holy” is “set apart from that which is commonplace, special, unique.” The Lord’s holiness is first and foremost his transcendent sovereignty as the ruler of the world. He is “set apart” from the world over which he rules. At the same time his holiness encompasses his moral authority, which derives from his royal position. As king he has the right to dictate to his subjects how they are to live; indeed his very own character sets the standard for proper behavior. This expression is a common title for the Lord in the book of Isaiah.

sn The text here uses an implied comparison (a figure of speech known as hypocatastasis): It compares the perfection of every word from God with some precious metal that has been refined and purified (e.g., Ps 12:6). The point is that God’s word is trustworthy; it has no defects and flaws, nothing false or misleading. The second half of the verse explains the significance of this point – it is safe to trust the Lord.

tn The comparative “like” does not appear in the Hebrew text, but is implied by the metaphor; it is supplied in the translation for the sake of clarity.

sn The line uses two more figures of speech to declare that God can be trusted for security and salvation. “Shield” is a simple metaphor – God protects. “Take refuge” is another implied comparison (hypocatastasis) – God provides spiritual rest and security for those who put their trust in him.
