Why did God kill Uzzah?
For trying to keep the ark from falling (by touching it)
And the anger of the LORD was kindled against Uzzah; and God smote him there for his error;
and there he died by the ark of God.
2 Samuel 6:6And when they came to Nachon's threshingfloor , Uzzah put forth his hand to the ark of God, and took
hold of it; for the oxen shook it.
And the anger of the LORD was kindled against Uzzah; and God smote him there for his error;
and there he died by the ark of God.
2 Samuel 6:6
