Deuteronomy 3:15-20

15And I gave Gilead unto Machir.

16And unto the Reubenites and unto the Gadites I gave from Gilead even unto the valley of Arnon, the middle of the valley, and the border thereof; even unto the river Jabbok, which is the border of the children of Ammon;

17the Arabah also, and Jordan and the border thereof, from Chinnereth even unto the sea of the Arabah, the Salt Sea, under the slopes of Pisgah eastward.

18And I commanded you at that time, saying, The LORD your God hath given you this land to possess it: ye shall pass over armed before your brethren the children of Israel, all the men of valour.

19But your wives, and your little ones, and your cattle, (I know that ye have much cattle,) shall abide in your cities which I have given you;

20until the LORD give rest unto your brethren, as unto you, and they also possess the land which the LORD your God giveth them beyond Jordan: then shall ye return every man unto his possession, which I have given you.
