'Tested' in the Bible

Then he cried to Yahweh. Yahweh showed him a tree, and he threw it into the waters, and the waters were made sweet. There he made a statute and an ordinance for them, and there he tested them;

He called the name of the place Massah, and Meribah, because the children of Israel quarreled, and because they tested Yahweh, saying, "Is Yahweh among us, or not?"
