The answer is: Massah & Meribah

Ex 17:7 - Massah means testing and Meribah means quarrel.

In the rolling narrative of the Exodus, Moses confronted not only daunting events but also unyielding struggles with his own people. During their journey through the wilderness, frustrations ran high, and the thirst that Israel's congregation experienced led them to push back against their leader. Here at Massah and Meribah, they challenged both Moses and indirectly their God, questioning whether He truly cared for them.

You might find it interesting that Massah and Meribah are often used in scripture as symbols of doubt and rebellion. This incident reminds us of humanity's constant struggle between faith and fear. In Psalms 95:8-9, we see this episode echoed distinctly, underscoring how those same quarrels can come to represent a hardening of hearts when we fail to remember past blessings and miraculous deliveries.

Fun trivia: Moses' name itself carries a dramatic connotation—derived from the Hebrew word for "draw out," as he was literally drawn from the water as a baby! If we juxtapose his beginnings against the continuing challenges of leading a sometimes recalcitrant people, his deep connection with water indeed makes us reflect on how thirst, both literal and metaphorical, can provoke supplication—the need for growth during hardship.

Ultimately, this episode isn’t just a tale of conflict but stirs our understanding of the essential relationship between emotional struggles and spiritual questioning. It's a reminder valuable even today: that quarreling may often underscore our deepest desires for connection and meaning.
