Revised Standard Version and Contemporary English Version begin a new paragraph here. This is logical as the two women now leave the house.

Then they went out to the city gate of Bethulia: Good News Translation and Contemporary English Version helpfully identify the subject as “the two women.” The “house” (Good News Translation) is not mentioned in the Greek text, but clearly implied in went out. Judith and her maid had been in Judith’s house while making their preparations. Contemporary English Version supplies the information that they “walked” to the gate: “Together the two women left the house and walked to the gate of Bethulia.” Good News Translation assumes the readers will remember Bethulia is a town, and omits the word city with reference to the gates. Other translators may wish to ensure understanding and include it.

Found Uzziah standing there with the elders of the city, Chabris and Charmis: “Standing guard” (Good News Translation) is not necessarily implied in the text, though it may be legitimately read from it. Most versions have the three men simply standing there—presumably not loitering, but seeing to their official duties. The town gates were equivalent to the courthouse—the place where official business was conducted. Rather than have the three just standing about, or standing guard, which was probably being done by the other male citizens, one could say that “they … found Uzziah and … Chabris and Charmis at their post of duty.” New Jerusalem Bible, however, has found the best solution. The men are “waiting” there. In 8.33 Judith had told them her plans, and that they should stand waiting for her at the gates. Perhaps the best rendering here would be “they came to the town gates and found Uzziah and … Charmis standing there waiting.” For elders see 6.16.
