Psalms 5:10
Brenton's English Septuagint · Berean Standard Bible
For there is no truth in their mouth; their heart is vain; their throat is an open sepulchre; with their tongues they have used deceit.
5:9
For not a word they speak can be trusted; destruction lies within them. Their throats are open graves; their tongues practice deceit (note: Or flattery; cited in Romans 3:13).
