Jamieson, Fausset & Brown, on Isa 11:12

“And he shall set up a standard unto the nations, and shall assemble the fugitives of Israel, and shall gather together the dispersed of Juda from the four quarters of the earth.”

“In the first restoration Judah alone was restored, with perhaps some few of Israel (the ten tribes): in the future restoration both are expressly specified (Eze 37:16-19; Jer 3:18). To Israel are ascribed the "outcasts" (masculine); to Judah the "dispersed" (feminine), as the former have been longer and more utterly castaways (though not finally) than the latter (Joh 7:52). The masculine and feminine conjoined express the universality of the restoration. from the four corners of the earth--Hebrew, "wings of the earth."”
