uW Translation Notes:

Note 1 topic: translate-symaction

וַ⁠יַּצִּ֧בוּ עָלָ֛י⁠ו גַּל־אֲבָנִ֖ים גָּד֣וֹל מְאֹ֑ד

(Some words not found in UHB: and=they_took DOM ʼAⱱīshālōm and,they_threw DOM=him/it in,forest to/towards the,pit (the),great and,they_set_up on/upon/above=him/it heap_of stones big/great very and=all Yisrael fled (a)_man ,,his )

In this culture, piling a heap of stones over a grave was a way putting shame on the person who had died. The Israelites had done this, for example, to Achan in Joshua 7:26. Some interpreters believe that in this case, it was also symbolic of the stoning that the Law of Moses said was the penalty for a rebellious son (Deuteronomy 21:18–21). If it would be helpful to your readers, you could explain the significance of this action in the text or in a footnote. Alternate translation: [and to shame him, they set over him a very great heap of stones]

Note 2 topic: figures-of-speech / idiom

אִ֥ישׁ ל⁠אהל⁠ו

(a)_man ,,his

The author is using a man to his tent as a common expression of his culture to mean that the soldiers stopped their military campaign altogether and each of them went back to his home and family. If this phrase does not have that meaning in your language, you could use a comparable expression from your language that does have that meaning, or you could state the meaning plainly. Alternate translation: [abandoning the army and returning home]
