uW Translation Notes:

Note 1 topic: grammar-connect-time-simultaneous

אִם־זְכַרְתִּ֥י⁠ךָ עַל־יְצוּעָ֑⁠י

(Some words not found in UHB: as best and,fatness satisfied self_of,my and,lips_of joyful praise mouth_of,my )

The word When indicates that David remembering God occurred at the same time as when he meditates on God. If it would be helpful to your readers, you could describe the time relationship more explicitly. Alternate translation: [As I remember you on my bed]

Note 2 topic: translate-unknown

בְּ֝⁠אַשְׁמֻר֗וֹת

(Some words not found in UHB: as best and,fatness satisfied self_of,my and,lips_of joyful praise mouth_of,my )

The term night watches refers to the divisions of the night during which guards were on duty. In ancient Israel, the night was typically divided into three or four such periods. If your readers would not be familiar with this, you could use a more general term. Alternate translation: [during the night] or [in the hours of the night]

Note 3 topic: figures-of-speech / parallelism

אִם־זְכַרְתִּ֥י⁠ךָ עַל־יְצוּעָ֑⁠י בְּ֝⁠אַשְׁמֻר֗וֹת אֶהְגֶּה־בָּֽ⁠ךְ

(Some words not found in UHB: as best and,fatness satisfied self_of,my and,lips_of joyful praise mouth_of,my )

These two phrases mean basically the same thing. The second 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: [When I remember you on my bed, yes, when I meditate on you in the night watches]
