The story appears in Exodus 17:1-7. Moses gave the site a double-trouble name, in Hebrew: Massah and Meribah. Massah means “test,” as in getting pushy with God. Meribah means “complain,” “argue,” or “fight.” The Israelites continued their pattern of pushing against God. That got them sentenced to 40 years in the desert badlands, south of what is now Israel. The location of the site is unknown. Exodus 17 puts it somewhere between the Israelite campsite at Rephidim and Mount Sinai. Those two sites appear to have been within walking distance, as the Exodus story reports it. Numbers 32:51, however, seems to place it near the oasis of Kadesh in the Zin Desert.
