 Some on Ebal, and some on Gerizim: 
 before the priests and the Levites, which bare the ark of the covenant
 of the Lord;
 it being brought out of the tabernacle on this occasion, and bottle by the priests and Levites: 
 as well the stranger, as he that was born among them;
 that is, as well the proselytes as the native Israelites, both appeared and were in the same situation: 
 half of them over against Mount Gerizim;
 that is, half of the tribes, and these were Simeon, Levi, Judah, Issachar, Joseph, and Benjamin: 
 and half of them over against Mount Ebal;
 which were the tribes of Reuben, Gad, Asher, Zebulun, Dan, and Naphtali; (See Gill on  Deuteronomy 27:12) and (See Gill on  Deuteronomy 27:13); 
 as Moses the servant of the Lord had commanded before, that they
 should bless the people of Israel,
 as in ( Deuteronomy 27:12 ) .
