uW Translation Notes:

Note 1 topic: figures-of-speech / parallelism

כִּ֭י יִתְחַמֵּ֣ץ לְבָבִ֑⁠י וְ֝⁠כִלְיוֹתַ֗⁠י אֶשְׁתּוֹנָֽן

that/for/because/then/when embittered heart,my and,heart,my pricked

The clause When my heart was embittered and the clause I was pierced in my kidneys mean basically the same thing. The second clause emphasizes the meaning of the first by repeating the same idea with different words. Hebrew poetry was based on this kind of repetition, and it would be good to show this to your readers by including both phrases in your translation rather than combining them. However, if it would be helpful to your readers, you could connect the phrases with a word other than and in order to show that the second phrase is repeating the first one, not saying something additional. Alternate translation: “When my heart was embittered, yes, when I was pierced in my kidneys”
