'Sabbath day' in the Bible

Then returned they unto Jerusalem from the mount called Olivet, which is nigh unto Jerusalem, a Sabbath day's journey off.

But they, passing through from Perga, came to Antioch of Pisidia; and they went into the synagogue on the sabbath day, and sat down.

And on the sabbath day we went forth without the gate by a river side, where we supposed there was a place of prayer; and we sat down, and spake unto the women that were come together.
