'Sabbath' in the Bible

and the Pharisees having seen, said to him, 'Lo, thy disciples do that which it is not lawful to do on a sabbath.'

'Or did ye not read in the Law, that on the sabbaths the priests in the temple do profane the sabbath, and are blameless?

for the son of man is lord even of the sabbath.'

and pray ye that your flight may not be in winter, nor on a sabbath;
