40Many times our ancestors rebelled against God in the desert and caused him to become very sad.
41Many times they did evil things, to find out if they could do those things without God punishing them. They frequently caused the holy God of Israel to become disgusted/sad.
40How oft made they him wroth in desert; they stirred him into ire in a place without water. (How often they made him angry in the wilderness; yea, they stirred him to anger in a place without water.)
41And they were turned, and tempted God; and they wrathed the holy of Israel. (Again and again they tempted God; and they angered the Holy One of Israel.)
