Kurieuo denotes exercising mastery or authority over persons, life and death, faith, or those who rule.

The attested uses chiefly describe an authority that has mastery over someone or something: death over Christ, sin over its hearers, and law over a person. It also describes rulers exercising authority over others, rejects such control over another's faith, and presents Christ and the Sovereign as Lord over the dead, living, and rulers.

1. Exercising controlling authority · dominant

   In Romans 6:9 the present active form is used where the APB renders death as no longer having “dominion over” Christ; Romans 6:14 similarly states that sin will not have dominion over its hearers. In Romans 7:1, the same present form occurs in the statement that law has authority over a person while he lives.

2. Ruling over other people · common

   In Luke 22:25, the present active plural form describes Gentile kings in relation to those under them; the APB renders the clause “lord it over them.” In 2 Corinthians 1:24, the first-person present form occurs in a denial of exercising such authority over the readers' faith.

3. Lordship over the dead, living, and rulers · common

   In Romans 14:9, the aorist active subjunctive states the purpose that Christ might be Lord of both the dead and the living. In 1 Timothy 6:15, the present active masculine plural participle occurs in the description “the Lord of those who rule,” alongside the Sovereign and King.

In the Anselm Project Bible: The APB uses “lord it over” in Luke 22:25, “lord over” in 2 Corinthians 1:24, and “dominion” or “authority” in the Romans verses. In Romans 14:9 and 1 Timothy 6:15 it uses “Lord”; these are verse-level renderings rather than definitions.
