Exodus 17:1–7 (Listen)
Water from the Rock
17:1 All the congregation of the people of Israel moved on from the wilderness of Sin by stages, according to the commandment of the LORD, and camped at Rephidim, but there was no water for the people to drink. 2 Therefore the people quarreled with Moses and said, “Give us water to drink.” And Moses said to them, “Why do you quarrel with me? Why do you test the LORD?” 3 But the people thirsted there for water, and the people grumbled against Moses and said, “Why did you bring us up out of Egypt, to kill us and our children and our livestock with thirst?” 4 So Moses cried to the LORD, “What shall I do with this people? They are almost ready to stone me.” 5 And the LORD said to Moses, “Pass on before the people, taking with you some of the elders of Israel, and take in your hand the staff with which you struck the Nile, and go. 6 Behold, I will stand before you there on the rock at Horeb, and you shall strike the rock, and water shall come out of it, and the people will drink.” And Moses did so, in the sight of the elders of Israel. 7 And he called the name of the place Massah1 and Meribah,2 because of the quarreling of the people of Israel, and because they tested the LORD by saying, “Is the LORD among us or not?”

The Pharisees and Sadducees Demand Signs
16:1 And the Pharisees and Sadducees came, and to test him they asked him to show them a sign from heaven. 2 He answered them,1 “When it is evening, you say, ‘It will be fair weather, for the sky is red.’ 3 And in the morning, ‘It will be stormy today, for the sky is red and threatening.’ You know how to interpret the appearance of the sky, but you cannot interpret the signs of the times. 4 An evil and adulterous generation seeks for a sign, but no sign will be given to it except the sign of Jonah.” So he left them and departed.
The Leaven of the Pharisees and Sadducees
5 When the disciples reached the other side, they had forgotten to bring any bread. 6 Jesus said to them, “Watch and beware of the leaven of the Pharisees and Sadducees.” 7 And they began discussing it among themselves, saying, “We brought no bread.” 8 But Jesus, aware of this, said, “O you of little faith, why are you discussing among yourselves the fact that you have no bread? 9 Do you not yet perceive? Do you not remember the five loaves for the five thousand, and how many baskets you gathered? 10 Or the seven loaves for the four thousand, and how many baskets you gathered? 11 How is it that you fail to understand that I did not speak about bread? Beware of the leaven of the Pharisees and Sadducees.” 12 Then they understood that he did not tell them to beware of the leaven of bread, but of the teaching of the Pharisees and Sadducees.
