You will not need to fight in this battle is literally “[It is] not to you to fight in this [battle]” (similarly New Jewish Publication Society’s Tanakh). Revised English Bible captures the meaning well with “It is not you who will fight this battle.” God will defeat the enemy as he did the Egyptians at the time of the Exodus (see Exo 14.13-14).

Take your position, stand still: Good News Translation provides a helpful model here with “Just take up your positions and wait.”

And see the victory of the LORD on your behalf: If this clause is still a part of the quotation in which the LORD is speaking, then it will be more natural in many languages to avoid using the third person. Parole de Vie, for example, translates “and look at how I, the LORD, will deliver you.”

O Judah and Jerusalem will be better translated in some languages as “you people of Jerusalem and the rest of Judah.”

Fear not and be not dismayed: See the comments on verse 15 where the same wording is used, except that verse 15 has an emphatic second person plural pronoun. Good News Translation translates be not dismayed differently here, but there is no reason to do so.

Tomorrow go out against them may be rendered “Tomorrow march out toward them” ( NET Bible).

And the LORD will be with you: Jahaziel tells the people of Judah that the LORD will help them as promised in Deut 20.1-4. As noted above, there is some question about where the embedded quotation of the LORD ends. If it ends here, then it will be unnatural in most languages to have the LORD refer to himself in the third person and some adjustment will have to be made to this clause; for example, Parole de Vie says “and I, the LORD, I will be with you.”
