As noted in the comments on verse 15, Dedan was an oasis in the Arabian Desert. It was about 800 kilometers (500 miles) south of Tyre. It stood on the major trade route from southern Arabia. Traded with you may be rendered “sold to you.” What Dedan traded with Tyre were saddlecloths for riding, that is, blankets to spread over the back of a horse before putting the saddle on. Some translations say “saddle blankets” (Good News Translation, Contemporary English Version, New International Version, New International Reader’s Version, New Living Translation), and New American Bible has “riding gear.” In areas where people do not know about riding horses, translators may use a descriptive phrase such as “blankets to put on horses when people ride them.”
