Concise Bible Dictionary:
A disciple whom Jesus loved: she was apparently the head of the household at Bethany, which Jesus at times visited. Martha was probably the widow of Simon a leper (compare Matt. 26:6-13 with John 12:1-8), and superintended domestic arrangements. She received the Lord into “her house” (Luke 10:38). Having the Lord for a visitor she was burdened with much service, and begged Him to instruct her sister Mary to help her. A contrast is here drawn between the two sisters: the one occupied with what she could do for the Lord; the other with what He was: self being plainly uppermost in Martha, while the Lord Himself was paramount with Mary. “That good part” should not be taken from her. But in John 12, when the Lord was again at Bethany, and they made a supper for Him, Martha’s service is in no way qualified, the raising up by the Lord of her brother Lazarus, and His dealings with herself, having doubtless taught her the needed lesson. Service in communion with Himself is acceptable to Him
