OET interlinear 1SA 31:3

uW Translation Notes:

Note 1 topic: figures-of-speech / metaphor

וַ⁠תִּכְבַּ֤ד הַ⁠מִּלְחָמָה֙ אֶל־שָׁא֔וּל

and,pressed_hard the,battle to/towards Shāʼūl

The author is speaking of the battle as if it were a heavy physical weight pressing down on Saul. If it would be clearer in your language, you could state the meaning plainly. Alternate translation: [And the Philistines fought fiercely against Saul]

Note 2 topic: figures-of-speech / explicit

וַ⁠יִּמְצָאֻ֥⁠הוּ הַ⁠מּוֹרִ֖ים אֲנָשִׁ֣ים בַּ⁠קָּ֑שֶׁת & מֵ⁠הַ⁠מּוֹרִֽים

and,found,him the,archers men in/on/at/with,bow & by,the,archers

Since the term shooters could describe either soldiers throwing javelins or soldiers launching arrows, the author adds the phrase the men with the bow to clarify his meaning. Your language may have a single term that you can use in your translation. Alternate translation: [And the archers … from the archers]

Note 3 topic: figures-of-speech / explicit

וַ⁠יָּ֥חֶל מְאֹ֖ד מֵ⁠הַ⁠מּוֹרִֽים

and,wounded very by,the,archers

By this phrase, the author means that Saul was in great pain because the archers had wounded him with arrows. You could indicate this explicitly in your translation if that would be helpful to your readers. Alternate translation: [And he writhed greatly in pain because the archers had wounded him with arrows]
