Joshua 22:11-21

11 And the children of Israel heard say, Behold, the sons of Ruben, and the sons of Gad, and the half tribe of Manasse have built an altar at the borders of the land of Chanaan at Galaad of Jordan, on the opposite side to the children of Israel.
12 And all the children of Israel gathered together to Selo, so as to go up and fight against them.
13 And the children of Israel sent to the sons of Ruben, and the sons of Gad, and to the sons of the half tribe of Manasse into the land of Galaad, both Phinees the son of Eleazar the son of Aaron the priest,
14 and ten of the chiefs with him; one chief of every household out of all the tribes of Israel; (the heads of families are the captains of thousands in Israel.)
15 And they came to the sons of Ruben, and to the sons of Gad, and to the half tribe of Manasse into the land of Galaad; and they spoke to them, saying,
16 Thus says the whole congregation of the Lord, What this transgression that ye have transgressed before the God of Israel, to turn away today from the Lord, in that ye have built for yourselves an altar, so that ye should be apostates from the Lord?
17 Is the sin of Phogor too little for you, whereas we have not been cleansed from it until this day, though there was a plague among the congregation of the Lord?
18 And ye have this day revolted from the Lord; and it shall come to pass if ye revolt this day from the Lord, that to-morrow there shall be wrath upon all Israel.
19 And now if the land of your possession little, cross over to the land of the possession of the Lord, where the tabernacle of the Lord dwells, and receive ye an inheritance among us; and do not become apostates from God, neither do ye apostatize from the Lord, because of your having built an altar apart from the altar of the Lord our God.
20 Lo! did not Achar the of Zara commit a trespass of the accursed thing, and there was wrath on the whole congregation of Israel? and he himself died alone in his own sin.
21 And the sons of Ruben, and the sons of Gad, and the half tribe of Manasse answered, and spoke to the captains of the thousands of Israel, saying,

Joshua 22:11-21 Meaning and Commentary

INTRODUCTION TO JOSHUA 22

The war with the Canaanites being ended, Joshua called to him the two tribes of Reuben and Gad, and the half tribe of Manasseh, who came over Jordan with him to assist in it, and commended them for their obedience to Moses and to himself, and to God by them; and then dismissed them, with some instructions to keep the ways and worship of God, and with his blessing upon them, Jos 22:1-8; upon which they returned to their country, and when they came to the borders of it set up an altar by Jordan, Jos 22:9,10; which, when the children of Israel heard of, it gave them great offence, they fearing they were going to make a revolt from the pure worship of God, and therefore sent a deputation of princes to them, with the son of the high priest, to inquire into the matter, and expostulate with them about it, who did, Jos 22:11-20; and who received from them a very satisfactory answer, Jos 22:21-31; with which they returned and reported to the children of Israel, and which gave them pleasure, Jos 22:32-34.
