What is the meaning of [He who excuses himself accuses himself]

We suspect that the person who makes too many excuses because he is probably
covering up his ill actions. It is better to admit a thing frankly than to
make excuse, for the excuses are such obvious evasions that they irritate
instead of convincing.
