'Sabbath day' in the Bible

Then they returned to Jerusalem from the Mount of Olives, which is near Jerusalem, a Sabbath day's journey away.

They left Perga and arrived in Antioch in Pisidia. On the Sabbath day, they went into the synagogue and sat down.

On the Sabbath day, we went out the city gate and walked along the river, where we thought there was a place of prayer. We sat down and began talking to the women who had gathered there.
