'Head' in the Bible

God has put everything under the Messiah's feet and has made him the head of everything for the good of the church,

Instead, by speaking the truth in love, we will grow up completely and become one with the head, that is, one with the Messiah,

For the husband is the head of his wife as the Messiah is the head of the church. It is he who is the Savior of the body.
