How do we know Jesus is referred to as both Jehovah and Adonai?

In Psalm 8, David addresses God using the names Jehovah and Adonai, which signify His nature and authority. Jehovah, the covenant name for God, emphasizes His commitment to fulfill His promises, while Adonai speaks to His lordship, particularly in the person of Jesus Christ. This duality encapsulates the full essence of Christ as both God and man. In the New Testament, Jesus affirms this understanding by quoting Psalm 8 in relation to Himself, highlighting the connection between David’s praise and His messianic mission. Thus, these names underscore the incarnation of Christ, wherein He takes on human form while retaining His divine essence as the eternal God.
