Lydia

Paul heard that a group of people met by the river to worship on the Sabbath day, so they went outside the city gate to the meeting place.
They sat down and began to speak to the women who were gathered there to pray. One of them was a woman named Lydia who was from the city of Thyatira  which was in a district east of Macedonia. She was a dealer who sold purple cloth.

The beautiful cloth was mainly used by members of the royal families and Roman senators who were required to have a purple band around the edge of their togas, or robes.

As Paul preached, the Lord opened the heart of Lydia to receive the message about Jesus. She believed his words and responded to the teaching. She and the members of her household were baptized.
She told the men if they considered her a believer in the Lord, she would like for them to come and stay at her house. Evidently she had plenty of room to accommodate the four of them; Paul, Silas, Timothy, and Luke was with them also. She continued to urge them and they accepted her invitation and stayed at her house.
Lydia's heart was like the good soil in the parable of the sower. When she heard the word of God, she received it with joy and obeyed the words of the apostle.
