OET interlinear JOS 18:3

uW Translation Notes:

Note 1 topic: figures-of-speech / synecdoche

אֶל בְּנֵ֣י יִשְׂרָאֵ֑ל

to/towards sons_of Yisrael

The context makes clear that the author is using an entire group, the sons of Israel, to mean one part of that group, the Israelite tribes that had not yet received any land. If it would be helpful in your language, you could state the meaning plainly. Alternate translation: “to the leaders of those tribes”

Note 2 topic: figures-of-speech / rquestion

עַד אָ֨נָה֙ אַתֶּ֣ם מִתְרַפִּ֔ים לָ⁠בוֹא֙ לָ⁠רֶ֣שֶׁת אֶת הָ⁠אָ֔רֶץ אֲשֶׁר֙ נָתַ֣ן לָ⁠כֶ֔ם יְהוָ֖ה אֱלֹהֵ֥י אֲבֽוֹתֵי⁠כֶֽם

until how? you_all slack about,going_in to,take_possession_of DOM the=earth/land which/who he/it_gave to/for=you_all YHWH god_of fathers_of,your_all's

Joshua is using the question form for emphasis. If a speaker of your language would not use the question form for that purpose, you could translate this as a statement or as an exclamation. Alternate translation: “You must stop being so slow to enter and take possession of the land that Yahweh, the God of your fathers, has given to you!”

Note 3 topic: figures-of-speech / metaphor

אֲבֽוֹתֵי⁠כֶֽם

fathers_of,your_all's

Joshua is speaking as if these people were the actual fathers of the current generation. If it would be clearer in your language, you could state the meaning plainly. Alternate translation: “your ancestors”
