Genesis 25:6 - Wesley's Explanatory Notes

He gave gifts — Or portions to the rest of his children, both to Ishmael, though at first he was sent empty away, and to his sons by Keturah. It was justice to provide for them; parents that do not that, are worse than infidels. It was prudence to settle them in places distant from Isaac, that they might not pretend to divide the inheritance with him. He did this while he yet lived, lest it should not have been done, or not so well done afterwards. In many cases it is wisdom for men to make their own hands their executors, and what they find to do, to do it while they live. These sons of the concubines were sent into the country that lay east from Canaan, and their posterity were called the children of the east, famous for their numbers. Their great increase was the fruit of the promise made to Abraham, that God would multiply his seed.
