Adam Clarke's Bible Commentary Verse 6. They reap every one his corn in the field ] This is perfectly characteristic. These wandering hordes often make sudden irruptions, and carry off the harvest of grain, olives, vines, &c., and plunge with it into the wilderness, where none can follow them. The Chaldee gives the same sense: "They reap in a field that is not their own, and cut off the vineyard of the wicked."
Matthew Henry Commentary
Verses 1-12 - Job discourses further about the prosperity of the wicked. That man live at ease who are ungodly and profane, he had showed, ch. xxi. Her he shows that many who live in open defiance of all the laws of justice, succeed in wicked practices; and we do not see them reckone with in this world. He notices those that do wrong under pretence of law and authority; and robbers, those that do wrong by force. He says "God layeth not folly to them;" that is, he does not at once send his judgments, nor make them examples, and so manifest their folly to all the world. But he that gets riches, and not by right, at his end shal be a fool, Jer 17:11.
