They that make them are like unto them,.... Are as blind, stupid, and senseless as they; or "let them that make them", &c. (q); so some versions and interpreters; See Gill on Psalm 115:8;
so is everyone that trusteth in them; alike ignorant and sottish: and so are all such that set up idols and lusts in their own hearts, and serve them; or trust to their own righteousness; even all unregenerate and self-righteous persons: they cannot speak a word for God and his grace, for Christ and his righteousness, for the Spirit of God, and his work upon their hearts, of all which they are ignorant; they are blind and have no sight and sense of their sin and misery, and of their need of Christ and his righteousness; they are deaf to his Gospel, and the charming voice of it; they are lifeless and breathless, are dead in trespasses and sins, and have no pantings and desires after spiritual things.
(q) So V. L. Pagninus, Montanus, Tigurine version, Sept. Syr. Arab. Ethiop.

are like unto them--or, "shall be like," &c. Idolaters become spiritually stupid and perish with their idols (Isaiah 1:31).
