'Cause' in the Bible

He went out to the spring and threw the salt in. Then he said, "This is what the Lord says, 'I have purified this water. It will no longer cause death or fail to produce crops."

Hazael asked, "Why are you crying, my master?" He replied, "Because I know the trouble you will cause the Israelites. You will set fire to their fortresses, kill their young men with the sword, smash their children to bits, and rip open their pregnant women."

Jehu said, "Come with me and see how zealous I am for the Lord's cause." So he took him along in his chariot.
