Meanings

[In LXX, for אָח; ]

1. lit. of a brother (Genesis 4:2, and elsewhere).

2. Of a neighbour (Leviticus 19:17).

3. Of a member of the same nation (Exodus 2:14, Deuteronomy 15:3). In NT in each of these senses (1. Matthew 1:2, and elsewhere; 2. Matthew 7:3; 3. Romans 9:3) and also

4. of a fellow-Christian: 1 Corinthians 1:1, Acts 9:30. This usage finds illustration in π., where ἀ. is used of members of a pagan religious community. The ἀδελφοὶ τ. Κυρίου (Matthew 12:46-49, Matthew 13:55, Matthew 28:10, Mark 3:31-34, Luke 8:19-21, John 2:12, John 7:3, John 7:5, John 7:10, John 20:17, Acts 1:14, 1 Corinthians 9:5) may have been sons of Joseph and Mary or of Joseph by a former marriage, but the view of Jerome, which makes ἀ. equivalent to ἀνεψιός, is inconsistent with Greek usage.
