Jesus, when saying that “the mild-tempered ones . . . will inherit the earth,” drew upon Psalm 37, which also says: “The righteous themselves will possess the earth, and they will reside forever upon it.” (Matt. 5:5; Ps. 37:10, 11, 29)
... The Scriptures also speak symbolically of a “new earth” where “death will be no more, neither will mourning nor outcry nor pain be anymore.”—Rev. 21:1-4; 2 Pet. 3:13.
