Let all those that seek thee,.... The Targum is, "that seek doctrine (or instruction) from thee.'' rejoice and be glad in thee; the Targum paraphrases it, "rejoice and be glad in thy word.'' and let such as love thy salvation say continually, let God be magnified; the Targum is, "let the glory of the Lord be increased;'' and in Psa 40:16, instead of "God", it is "the Lord", or "Jehovah": See Gill on Psa 40:16.
