'On the Sabbath' in the Bible

But they, going through from Perga, came to Antioch in Pisidia; and they went into the Synagogue on the Sabbath and were seated.

And when they went out, they made a request that these words might be said to them again on the Sabbath after.

And on the Sabbath after, almost all the town came together to give hearing to the word of God.

And on the Sabbath we went outside the town, by the river, where we had an idea that there would be a place of prayer; and, being seated, we had talk with the women who had come together.
