Now he was teaching in one of the synagogues on the Sabbath.  And behold, there was a woman who had had a disabling spirit for eighteen years. She was bent over and could not fully straighten herself.  When Jesus saw her, he called her over and said to her, “Woman, you are freed from your disability.”  And he laid his hands on her, and immediately she was made straight, and she glorified God.  But the ruler of the synagogue, indignant because Jesus had healed on the Sabbath, said to the people, “There are six days in which work ought to be done. Come on those days and be healed, and not on the Sabbath day.”  Then the Lord answered him, “You hypocrites! Does not each of you on the Sabbath untie his ox or his donkey from the manger and lead it away to water it?  And ought not this woman, a daughter of Abraham whom Satan bound for eighteen years, be loosed from this bond on the Sabbath day?”  As he said these things, all his adversaries were put to shame, and all the people rejoiced at all the glorious things that were done by him.
 He said therefore, “What is the kingdom of God like? And to what shall I compare it?  It is like a grain of mustard seed that a man took and sowed in his garden, and it grew and became a tree, and the birds of the air made nests in its branches.”
 And again he said, “To what shall I compare the kingdom of God?  It is like leaven that a woman took and hid in three measures of flour, until it was all leavened.”
(Luke 13:10-21 ESV)
 Therefore, while the promise of entering his rest still stands, let us fear lest any of you should seem to have failed to reach it.  For good news came to us just as to them, but the message they heard did not benefit them, because they were not united by faith with those who listened.  For we who have believed enter that rest, as he has said,
“As I swore in my wrath,
‘They shall not enter my rest,’”
although his works were finished from the foundation of the world.  For he has somewhere spoken of the seventh day in this way: “And God rested on the seventh day from all his works.”  And again in this passage he said,
“They shall not enter my rest.”
 Since therefore it remains for some to enter it, and those who formerly received the good news failed to enter because of disobedience,  again he appoints a certain day, “Today,” saying through David so long afterward, in the words already quoted,
“Today, if you hear his voice,
do not harden your hearts.”
 For if Joshua had given them rest, God would not have spoken of another day later on.  So then, there remains a Sabbath rest for the people of God,  for whoever has entered God's rest has also rested from his works as God did from his.
 Let us therefore strive to enter that rest, so that no one may fall by the same sort of disobedience.
(Hebrews 4:1-11 ESV)
