Klēros (G2819) means a lot (used for casting to determine outcomes), an allotted portion, or an inheritance. It carries the weight of divine apportionment — the share assigned to each person by God's sovereign decision.
The soldiers cast lots (klerus) for Jesus' garments, unknowingly fulfilling Psalm 22:18. The disciples cast lots to replace Judas — trusting God to direct the outcome (Acts 1:26). Peter warns against lording it over those 'entrusted to you' (literally 'your lots/allotments,' G2819). Every believer receives a kleros — an inheritance in the saints (Colossians 1:12), secured not by chance but by grace.
