uW Translation Notes:

Note 1 topic: writing-pronouns

וְ⁠אֶצְרְפֶ֥⁠נּוּ לְ⁠ךָ֖ שָׁ֑ם

so,that,I_may_test_it to/for=yourself(m) (Some words not found in UHB: and=he/it_said YHWH to/towards Gidˊōn again/more the,people many take_~_down ,them to/towards the=waters so,that,I_may_test_it to/for=yourself(m) there and=it_was which/who say to,you this go with,you he/it go with,you and=all/each/any/every which/who say to,you this not go with,you he/it not go )

The pronoun it refers back to the people earlier in the verse. It may be helpful to clarify this for your readers. Alternate translation: [and I will refine the people for you there]

Note 2 topic: figures-of-speech / metaphor

וְ⁠אֶצְרְפֶ֥⁠נּוּ לְ⁠ךָ֖

so,that,I_may_test_it to/for=yourself(m)

Yahweh is speaking as if he were literally going to refine Gideon’s troops, as if they were a precious metal such as silver or gold and he was going to melt them with heat to remove their impurities. He means that he is going to enable Gideon to identify the best soldiers and keep only them in his army. If it would be clearer in your language, you could state the meaning plainly. Alternate translation: [and I will enable you to identify the best soldiers]

Note 3 topic: figures-of-speech / quotesinquotes

וְ⁠הָיָ֡ה אֲשֶׁר֩ אֹמַ֨ר אֵלֶ֜י⁠ךָ זֶ֣ה ׀ יֵלֵ֣ךְ אִתָּ֗⁠ךְ ה֚וּא יֵלֵ֣ךְ אִתָּ֔⁠ךְ וְ⁠כֹ֨ל אֲשֶׁר־אֹמַ֜ר אֵלֶ֗י⁠ךָ זֶ֚ה לֹא־יֵלֵ֣ךְ עִמָּ֔⁠ךְ ה֖וּא לֹ֥א יֵלֵֽךְ

and=it_was (Some words not found in UHB: and=he/it_said YHWH to/towards Gidˊōn again/more the,people many take_~_down ,them to/towards the=waters so,that,I_may_test_it to/for=yourself(m) there and=it_was which/who say to,you this go with,you he/it go with,you and=all/each/any/every which/who say to,you this not go with,you he/it not go )

If it would be clearer in your language, you could translate this so that there is not a quotation within a quotation. Alternate translation: [And when I tell you that a certain kind of soldier is to go with you, then you must bring that kind of soldier with you, but you must not bring any other kind of soldier with you that I say is not to go with you]
