Klēróō (κληρόω) means to assign by lot, to allot, to obtain as one's inheritance. In the passive, it conveys being chosen or predestined — receiving one's portion by divine appointment rather than human merit.
Ephesians 1:11 uses the passive: believers 'have obtained an inheritance, having been predestined according to the plan of him who works out everything in conformity with the purpose of his will.' The theological weight is immense: salvation is by divine lot and election, not human achievement. God's people are His klēros — His chosen possession. This echoes Deuteronomy 32:9: 'the LORD's portion is his people, Jacob his allotted inheritance,' and connects to 1 Peter 2:9: 'a chosen people, a royal priesthood, God's special possession.'
