OET interlinear 1 SAM 30:23

uW Translation Notes:

Note 1 topic: writing-politeness

אֶחָ֑⁠י

my_brothers_of,my

Although David is the leader of this group of men, he is not using his authority to insist that they do as he says. Instead, he addresses the men who do not want to share the plunder as his brothers. In this context, the term means more than that they are fellow Israelites. David is using it to mean men who have just fought together (“brothers in arms”), as he describes in the next sentence. Your language may have a comparable term that you can use here in your translation.

Note 2 topic: grammar-connect-words-phrases

וַ⁠יִּשְׁמֹ֣ר

(Some words not found in UHB: and=he/it_said Dāvid not do so my_brothers_of,my DOM which/who he/it_gave YHWH to/for=us and,he_has_kept ,us and=he/it_gave DOM the_marauding,band [which],came on,us in,hand_of,our )

Here the word For introduces not a reason but a further explanation. Alternate translation: [After all he has kept]

Note 3 topic: figures-of-speech / metonymy

בְּ⁠יָדֵֽ⁠נוּ

(Some words not found in UHB: and=he/it_said Dāvid not do so my_brothers_of,my DOM which/who he/it_gave YHWH to/for=us and,he_has_kept ,us and=he/it_gave DOM the_marauding,band [which],came on,us in,hand_of,our )

David is using the term hand to represent power and control. If it would be helpful in your language, you could use an equivalent expression or plain language. Alternate translation: [into our power]
