'Adds' in the Bible

For he adds rebellion to his sin;he scornfully claps in our presence,while multiplying his words against God.

The Lord’s blessing enriches,and struggle adds nothing to it.

He adds:I will never again remembertheir sins and their lawless acts.

I testify to everyone who hears the prophetic words of this book: If anyone adds to them, God will add to him the plagues that are written in this book.
