Midrash sur Michée 4:8

Jacob took his sons and his grandsons, and his wives, and he went to Kirjath Arba (so as to be) near Isaac his father. And he found there Esau and his sons and his wives dwelling in the tents of Isaac. And he spread his tent apart from him; and Isaac saw Jacob, his wives, his daughters, and all that belonged to him, and he rejoiced in his heart exceedingly. Concerning him the Scripture saith, "Yea, thou shalt see thy children's children, peace be upon Israel" (Ps. 128:6).
