Exodus 17:1-7 (CEB)
The whole Israelite community broke camp and set out from the Sin desert to continue their journey, as the Lord commanded. They set up their camp at Rephidim, but there was no water for the people to drink. The people argued with Moses and said, "Give us water to drink."
Moses said to them, "Why are you arguing with me? Why are you testing the Lord?" But the people were very thirsty for water there, and they complained to Moses, "Why did you bring us out of Egypt to kill us, our children, and our livestock with thirst?"
So Moses cried out to the Lord, "What should I do with this people? They are getting ready to stone me."
The Lord said to Moses, "Go on ahead of the people, and take some of Israel's elders with you. Take in your hand the shepherd's rod that you used to strike the Nile River, and go. I'll be standing there in front of you on the rock at Horeb. Hit the rock. Water will come out of it, and the people will be able to drink." Moses did so while Israel's elders watched. He called the place Massah and Meribah, because the Israelites argued with and tested the Lord, asking, "Is the Lord really with us or not?"
Matthew 21:23-32 (CEB)
Jesus responded, "I assure you that if you have faith and don't doubt, you will not only do what was done to the fig tree. You will even say to this mountain, 'Be lifted up and thrown into the lake.' And it will happen. If you have faith, you will receive whatever you pray for."
When Jesus entered the temple, the chief priests and elders of the people came to him as he was teaching. They asked, "What kind of authority do you have for doing these things? Who gave you this authority?"
Jesus replied, "I have a question for you. If you tell me the answer, I'll tell you what kind of authority I have to do these things. Where did John get his authority to baptize? Did he get it from heaven or from humans?"
They argued among themselves, "If we say 'from heaven,' he'll say to us, 'Then why didn't you believe him?' But we can't say 'from humans' because we're afraid of the crowd, since everyone thinks John was a prophet." Then they replied, "We don't know."
Jesus also said to them, "Neither will I tell you what kind authority I have to do these things.
"What do you think? A man had two sons. Now he came to the first and said, 'Son, go and work in vineyard today.' "'No, I don't want to,' he replied. But later he changed his mind and went. "The father said the same thing to the other son, who replied, 'Yes, sir.' But he didn't go.
"Which one of these two did his father's will?" They said, "The first one."
Jesus said to them, "I assure you that tax collectors and prostitutes are entering God's kingdom ahead of you. For John came to you on the righteous road, and you didn't believe him. But tax collectors and prostitutes believed him. Yet even after you saw this, you didn't change your hearts and lives and you didn't believe him."
