uW Translation Notes:

Note 1 topic: figures-of-speech / parallelism

וַ⁠יִּטְמְא֥וּ בְ⁠מַעֲשֵׂי⁠הֶ֑ם וַ֝⁠יִּזְנוּ֗ בְּ⁠מַֽעַלְלֵי⁠הֶֽם

(Some words not found in UHB: and,they_became_unclean by,works_of,their and,they_played_the_prostitute by,deeds_of,their )

These two phrases And they became unclean by their deeds and and they prostituted themselves by their actions mean basically the same thing. The second phrase emphasizes the meaning of the first by repeating the same idea with different words. Hebrew poetry was based on this kind of repetition, and you may want to show this to your readers by including both phrases in your translation. If it is helpful, you could connect the phrases in a way that shows that the second phrase is repeating the first one, not saying something additional. Alternate translation: [And they became unclean by their deeds; indeed, they prostituted themselves by their actions]

Note 2 topic: figures-of-speech / metaphor

וַ⁠יִּטְמְא֥וּ

(Some words not found in UHB: and,they_became_unclean by,works_of,their and,they_played_the_prostitute by,deeds_of,their )

The psalmist is speaking as if the Israelites had become unclean physically through their sinful actions. He means that they became spiritually defiled or morally corrupted by their idolatrous practices. If it would be helpful in your language, you could state the meaning plainly. Alternate translation: [And they became very sinful]

Note 3 topic: figures-of-speech / metaphor

וַ֝⁠יִּזְנוּ֗

(Some words not found in UHB: and,they_became_unclean by,works_of,their and,they_played_the_prostitute by,deeds_of,their )

The psalmist is speaking as if the Israelites were unfaithful wives who prostituted themselves. He means that they violated their covenant relationship with Yahweh by worshiping idols. Your language may have a comparable expression that you can use in your translation, or you could state the meaning plainly. Alternate translation: [and they violated their relationship with Yahweh]
