As Caleb inherited the same land which his feet trod on (Deu 1:36; Jos 14:9), so Messiah and His saints shall inherit the renovated earth which once they trod while defiled by the enemy (Isa 34:4; Isa 51:16; Isa 66:22; Eze 21:27; Psa 2:8; Psa 37:11; Pe2 3:13; Heb 12:26-28 Rev 21:1). not be remembered--See on Isa 65:16, note on "troubles"; the words here answer to "the former . . . forgotten," &c. The former sorrows of the earth, under the fall, shall be so far from recurring, that their very remembrance shall be obliterated by the many mercies I will bestow on the new earth (Rev. 21:4-27).
