Proverbs 30:5

Every word of God [is] pure,.... The whole word of God. "All Scripture", given by inspiration of God, to which Agur directs, as giving the best account of God, of his name, nature, and perfections; of his Son, person, offices, and grace; being pure, very pure, "purified" z like silver, purified in a furnace of earth. The whole of Scripture is pure, free from all falsehood and error; coming from the God of truth, who cannot lie, and therefore called "the Scriptures of truth": every promise is pure as well as precious, made without dissimulation, faithfully performed, and all yea and amen in Christ; every doctrine is pure, free from the mixtures and inventions of men; the sincere milk of the word; consistent and all of a piece, not yea and nay; and tending to promote purity of heart and life; wholesome words, and doctrines according to godliness; see

Psalms 12:6;

he [is] a shield unto them that put their trust in him; not the word, but God, whose the word is; and which represents him as a proper object of trust, both with respect to things temporal and spiritual, at all times; and as a shield to protect such, by his power and grace, from all their enemies, sin, Satan, and the world, and also from all errors and false doctrines; see Psalms 3:3.
