Ecclesiasticus on swearing (Sir 27:14-16)
The Latin:
Narrátio peccántium odiósa,
et risus illórum in delíciis peccáti.
Loquéla multum iúrans horripilatiónem cápiti státuet,
et irreveréntia ipsíus obturátio áurium.
Effúsio sánguinis in rixa superbórum,
et maledíctio illórum audítus gravis.
The English:
The discourse of sinners is hateful,
and their laughter is at the pleasures of sin.
The speech that sweareth much shall make the hair of the head stand upright:
and its irreverence shall make one stop his ears.
In the quarrels of the proud is the shedding of blood:
and their cursing is a grievous hearing.
