Thou shalt not remove thy neighbour's landmark,.... By which one man's land is distinguished from another; for so to do is to injure a man's property, and alienate his lands to the use of another, which must be a very great evil, and render those that do it obnoxious to a curse, Deu 27:17. which they of old have set in thine inheritance, which thou shall inherit in the land that the Lord thy God giveth thee to possess it; the land of Canaan: this is thought to refer to the bounds and limits set in the land by Eleazar and Joshua, and those concerned with them at the division of it; when not only the tribes were bounded; and distinguished by certain marks, but every man's estate, and the possession of every family in every tribe which though not as yet done when this law was made, yet, as it respects future times, might be said to be done of old, whenever there was any transgression of it, which it cannot be supposed would be very quickly done; and it is a law not only binding on the inhabitants of the land of Canaan, but all others, it being agreeably to the light and law of nature, and which was regarded among the Heathens, Pro 22:28.
