Mary, Mother of Mark

Fausset's Bible Dictionary

Sister to Barnabas (KJV, Colossians 4:10), or rather aunt, since anepsios means "cousin," not commonly "sister's son. (See MARK.) As Barnabas gave up his lands, so she her house at Jerusalem for the use of the church. Peter's resorting there immediately upon his release (Acts 12:12) shows her tried steadfastness and implies a bond of intimacy with her; so that he calls Mark his "son" (1 Peter 5:13). The house was one of the church's worship rooms (Acts 2:46; Acts 20:8, compare Acts 4:24; Acts 4:31); "there many were gathered together praying" for Peter's deliverance, and God "heard, while they were yet speaking" (Isaiah 65:24). Mark doubtless derived some of the straightforward, decided character which appears in his Gospel from her influence. His attachment to her was probably one cause of his return to Jerusalem from Perga (Acts 13:13).
