uW Translation Notes:

Note 1 topic: figures-of-speech / infostructure

וַ⁠יִּקְשֹׁ֨ר עָלָ֜י⁠ו בַּעְשָׁ֤א בֶן־אֲחִיָּה֙ לְ⁠בֵ֣ית יִשָּׂשכָ֔ר וַ⁠יַּכֵּ֣⁠הוּ בַעְשָׁ֔א בְּ⁠גִבְּת֖וֹן אֲשֶׁ֣ר לַ⁠פְּלִשְׁתִּ֑ים וְ⁠נָדָב֙ וְ⁠כָל־יִשְׂרָאֵ֔ל צָרִ֖ים עַֽל־גִּבְּתֽוֹן

(Some words not found in UHB: and,he_conspired on/upon/above=him/it Baˊshāʼ son_of ʼAḩiy^yāh of,the_house_of Yissaskar and,he,struck_him_down Baˊshāʼ at,Gibbethon which/who [belonged]_to,Philistines and,Nadab and=all Yisrael laying_siege on/upon Gibtōn )

If it would be more natural in your language, you may want to put the information that Nadab and all of Israel were besieging against Gibbethon before the information that Baasha … conspired against Nadab. Alternate translation: [Now Nadab and all of Israel were besieging against Gibbethon, which is to the Philistines. And Baasha, the son of Ahijah, from the house of Issachar, conspired against him, and Baasha struck him at Gibbethon]

The author is introducing Baasha as a new participant in the story. Your language may have its own way of introducing new participants that you can use in your translation. Alternate translation: [There was a man named Baasha, the son of Ahijah, from the house of Issachar, and he conspired]

Note 3 topic: figures-of-speech / metaphor

The author is speaking of the tribe of Issachar as if it were actually a house. Your language may have a comparable expression that you can use in your translation, or you could state the meaning plainly. Alternate translation: [from the tribe of Issachar]

Note 4 topic: figures-of-speech / explicit

(Some words not found in UHB: and,he_conspired on/upon/above=him/it Baˊshāʼ son_of ʼAḩiy^yāh of,the_house_of Yissaskar and,he,struck_him_down Baˊshāʼ at,Gibbethon which/who [belonged]_to,Philistines and,Nadab and=all Yisrael laying_siege on/upon Gibtōn )

See how you translated the similar expression in 11:15. Alternate translation: [and Baasha killed him]
