Matthew Poole and continuators on Jeremiah 49:13

13 For I have sworn by my self, saith the LORD, that Bozrah shall become a desolation, a reproach, a wast, and a curse, and all the cities thereof shall be perpetual wastes .

As men when they would confirm their promise or threatning to do any thing, add an Oath to it, so doth God, who, having no greater to swear by, sweares by himself, chap. 44.26. that which God would here confirm was his threatning against Edom, exprest under the notion of Bozrah, (a part for the whole) Bozrah being its principal City, Isaiah 63.1. as well as a City of Moa[illegible: 1 letter], (as we found in the foregoing chapter) and that which he threatens it with was not being a reproach, a wast, and a curse for a time, but for ever.
