He named the place Massah and Meribah because the Israelites complained, and because they tested the Lord, saying, “Is the Lord among us or not?”

These are the waters of Meribah, where the Israelites quarreled with the Lord, and He showed His holiness to them.

“Aaron will be gathered to his people; he will not enter the land I have given the Israelites, because you both rebelled against My command at the waters of Meribah.

When the community quarreled in the Wilderness of Zin, both of you rebelled against My command to show My holiness in their sight at the waters.” Those were the waters of Meribah of Kadesh in the Wilderness of Zin.

He said about Levi:

Your Thummim and Urim belong to Your faithful one;
You tested him at Massah
and contended with him at the waters of Meribah.

You called out in distress, and I rescued you;
I answered you from the thundercloud.
I tested you at the waters of Meribah.Selah

Do not harden your hearts as at Meribah,
as on that day at Massah in the wilderness

They angered the Lord at the waters of Meribah,
and Moses suffered because of them;
