Isaiah 28:16-17

Therefore, this is what the Sovereign LORD says: “Look! I am placing a foundation stone in Jerusalem, a firm and tested stone. It is a precious cornerstone that is safe to build on. Whoever believes need never be shaken. I will test you with the measuring line of justice and the plumb line of righteousness. Since your refuge is made of lies, a hailstorm will knock it down. Since it is made of deception, a flood will sweep it away.
