Heritage
In some of the modern Eng. VSS there is a tendency to use “heritage” to emphasize spiritual matters (Deut. 9:26; Josh 18:7) and to use “inheritance” in contexts dealing with material affairs (Num 36:9; Deut 10:9). However, a clear distinction is not always possible.
International Standard Bible Encyclopedia (1915)
That which is allotted, possession, property, portion, share, peculiar right, inheritance; applied to land transferred from the Canaanites to Israel (Ps 11:6; 136:22); to Israel, as the heritage of Yahweh (Joe 3:2, etc.). In the New Testament (Eph 1:11) applied to believers, the spiritual Israel, as God’s peculiar possession (Ellicott, Eadie).
