Charles Spurgeon Commentary Mark 14:56-59

"For many bare false witness against him, and their witness agreed not together. And there stood up certain, and bare false witness against him, saying, We heard him say, I will destroy this temple that is made with hands, and in three days I will build another made without hands. And not even so did their witness agree together." — Mark 14:56-59 (ASV)
