In verse 3 Good News Translation has reversed the two lines, since words are meant to follow thoughts. The psalmist promises to speak wisdom, and his “thoughts will be clear” (Good News Translation).

What the psalmist is writing about is not philosophical knowledge but practical, everyday wisdom. To speak wisdom must be rendered in some languages as “I will speak words that will make you wise.”

Meditation of my heart: the word translated meditation occurs only here in the Old Testament; the related verb “to meditate” is used in 1.2 (see comments there).

The word translated understanding carries the idea of skill; New Jerusalem Bible and Bible en français courant have “good sense”; New Jerusalem Bible “my speech is full of insight.” Another possible version is “understanding guides my thoughts.”

Verse 3 is a clear case of heightening movement from line a to line b, in which meditation of my heart steps up the thought from the physical mouth of line a. The intensification may be made explicit in English by rendering, for example, “I will not only speak words of wisdom, but what is more, my deepest thoughts will be clearly expressed.” Translators may prefer to follow the logical order of thoughts before words, as Good News Translation has done; however, this is not the concern of the psalmist.

In verse 4 proverb and riddle are parallel. The Hebrew word translated proverb is mashal (see Howard A. Hatton, The Bible Translator, vol. 27, no. 2, April 1976, pages 224-230). Proverbs are sometimes called “wise sayings” or “wisdom words of the ancestors.” One can also translate verse 4a “I will ponder what I must teach.”

The psalmist promises to explain the proverb, calling it my riddle. Revised Standard Version solve does not mean that he, the psalmist, is going to discover for himself, for the first time, the meaning of his proverb. Rather, he is going to explain it to his listeners. Anderson suggests “perplexing problem” as the meaning of the latter word here.

Only here in the Old Testament is instruction given to the accompaniment of music, although in places prophetic utterance was so delivered (see 1 Sam 10.5; 2 Kgs 3.15). To the music of the lyre may be rendered in some languages “as I play on the stringed instrument called harp” or simply “as I play on the stringed instrument.”
