Massah

The place was named Massah [testing] and M'rivah [quarreling] because of the quarreling of the people of Isra'el and because they tested ADONAI by asking, "Is ADONAI with us or not?"

Do not put ADONAI your God to the test, as you tested him at Massah [testing].

"Again at Tav'erah, Massah and Kivrot-HaTa'avah you made ADONAI angry;

Of Levi he said: "Let your tumim and urim be with your pious one, whom you tested at Massah, with whom you struggled at M'rivah Spring.
