This proverb means that those who easily take oaths or swear often are often seen as unreliable, especially in terms of money. In society, excessive pledging can indicate a degree of dishonesty or an attempt to hide an unpleasant truth. The equivalent proverb in English could be: ‘He who swears easily is little believed’. A truly honest person wouldn’t need to swear often to prove their honesty, their actions would speak for themselves.
