dor'-kas (Dorkas, the Greek equivalent of Aramaic tabitha, "a gazelle"): The name was borne by a Christian woman of Joppa. She is called a disciple (mathetria: Acts 9:36, the only place in the New Testament where the feminine form is used). She seems to have had some means and also to have been a leader in the Christian community. Dorcas was beloved for the manner in which she used her position and means, for she "was full of good works, and almsdeeds which she did." Among her charities was the clothing of the poor with garments she herself made (Acts 9:39), and by following her example, numerous "Dorcas societies" in the Christian church perpetuate her memory. There is a local memorial in the "Tabitha School" in Jaffa devoted to the care and education of poor girls.
Her restoration to life by Peter is recorded. At the time of her death Peter was in Lydda where he had healed Aeneas. Being sent for, he went to Joppa, and, by the exercise of the supernatural powers granted to him, "he presented her alive" to the mourning community. In consequence of this miracle "many believed on the Lord" (Acts 9:42).

Dorcas (3 Occurrences)
Acts 9:36 Now there was at Joppa a certain disciple named Tabitha, which when translated, means Dorcas. This woman was full of good works and acts of mercy which she did. (WEB KJV WEY ASV BBE DBY WBS YLT NAS RSV NIV)
Acts 9:39 Peter got up and went with them. When he had come, they brought him into the upper chamber. All the widows stood by him weeping, and showing the coats and garments which Dorcas had made while she was with them. (WEB KJV WEY ASV BBE DBY WBS YLT NAS RSV NIV)
Acts 9:40 Peter, however, putting every one out of the room, knelt down and prayed, and then turning to the body, he said, "Tabitha, rise." Dorcas at once opened her eyes, and seeing Peter, sat up. (WEY)
