Concept:Moses gave the name "Massah and Meribah" because the Israelites tested God's presence at Rephidim.
Explanation:At Rephidim, the people found no water, so they quarrelled with Moses and made complaints against him.
They challenged whether God was truly among them by asking, "Is the LORD among us or not?" (Exodus 17:7).
God told Moses to strike the rock at Horeb, and he did so in the sight of the elders of Israel.
Water flowed from the rock, and the people drank.
Moses then called the place Massah, meaning "testing," and Meribah, meaning "strife" or "quarreling."
The biblical record shows that this name was given because the Israelites put the Lord to the proof.
Their attitude of asking whether God was with them was a direct test of the Almighty.
This makes testing the Lord the particular reason for the name.
Answer:A. They wanted to put the Lord to the test.
