'Sabbath Day' in the Bible

And he came to Nazareth, where he was brought up; and he entered, according to his custom, into the synagogue on the sabbath day, and stood up to read.

But the ruler of the synagogue, indignant because Jesus healed on the sabbath, answering said to the crowd, There are six days in which people ought to work; in these therefore come and be healed, and not on the sabbath day.

And this woman, who is a daughter of Abraham, whom Satan has bound, lo, these eighteen years, ought she not to be loosed from this bond on the sabbath day?

And answering he said to them, Of which of you shall an ass or ox fall into a well, that he does not straightway pull him up on the sabbath day?
