Charles Spurgeon Commentary 1 Chronicles 13:11-12

"And David was displeased, because Jehovah had broken forth upon Uzza; and he called that place Perez-uzza, unto this day. And David was afraid of God that day, saying, How shall I bring the ark of God home to me?" — 1 Chronicles 13:11-12 (ASV)

He was afraid that he also might die.
