Reference: Peculiar People, Or Treasure
Morish
Except in Ec 2:8, where 'the peculiar treasure of kings' is gathered by Solomon, these expressions both in the O.T. and in the N.T. refer to what God's people are to Him. Ex 19:5; De 14:2; 26:18; Ps 135:4; Tit 2:14. The terms imply a possession upon which a specially choice value is set. 1Pe 2:9 is a little different "Ye are 'a people for a possession': cf. Mal 3:17.
