Ibn Ezra on Psalms

"Praise be to God" - [These are] the words of the composer by way of prophecy, praising God as he sees his vision, for God will build Jerusalem and gather the dispersed of Israel. And the word "זמרה" is a verb, like [it says] "... [and I will continue] to discipline you..." (Vayikra 26:18), and the ה is added because it serves for that which is after. "For it is good to sing of God, for it is pleasant and desirable" - [this word נאוה] is from the morphology of the word תאוה (desire), as I have explained, for the word is in the נפעל (passive) conjugation, like [it says] "...and all that is made in a frying pan..." (Vayikra 7:9).

"[He will] build," "He will bring in" - like [it says] "Go, bring in all the Jews..." (Esther 4:16).

"He who heals the broken-hearted" - They are the mourners of Zion. "And bandages" - [this word is] like that [which it says]: "...they were not sprinkled [with medicinal herbs] and they were not bandaged/wrapped up..." (Isaiah 1:6). And Rabbi Yitzchak the Spaniard says that [this phrase is referring] to [how God "bandages" and fashions] their design, like the expression used by Yishmael and others like him: "Your hands designed me..." (Iyov 10:8). And in my opinion, [the meaning is] that He is like one who touches them, that he touches that which is very saddening for them.

His word runs - the reason for the double language, either on the way or on the clouds, who are commanded to quickly fulfill commands, so we are commanded to quicken.
