25 Then he cried out to the LORD , and the LORD showed him a tree; and he threw it into the waters, and the waters became sweet. There He made for them a statute and regulation, and there He tested them.

4 Then the LORD said to Moses, "Behold, I will rain bread from heaven for you; and the people shall go out and gather a day's portion every day, that I may test them, whether or not they will walk in My instruction.

2 Therefore the people quarreled with Moses and said, "Give us water that we may drink." And Moses said to them, "Why do you quarrel with me? Why do you test the LORD ?"

7 He named the place Massah and Meribah because of the quarrel of the sons of Israel, and because they tested the LORD , saying, "Is the LORD among us, or not?"

20 Moses said to the people, "Do not be afraid; for God has come in order to test you, and in order that the fear of Him may remain with you, so that you may not sin."
