Change error messages

Hi,
is it possible to customise the sitewide error messages that Woocommerce shows? I specifically want to change the error message on the payment screen after payment is submitted. The current message is

“Unfortunately your order cannot be processed as the originating bank/merchant has declined your transaction.

Please attempt your purchase again or go to your account page.”

Any help is greatly appreciated.

Regards.
MIles
