The author is referring to the Euphrates River, which was the most important river in this region and so was sometimes simply called the River. You could use your language’s name for this river if that would be helpful to your readers. See how you translated the similar expression in 8:3. Alternate translation: [the Euphrates River]

לִ⁠פְנֵי⁠הֶֽם

[was],before_of,them

This expression depicts Shobach as being in front of this combined army, and the author is using that position to represent his leadership of the army. If it would be helpful in your language, you could use an equivalent expression or plain language. Alternate translation: [was leading them] or [was commanding them]
