First reading: Wisdom 18:6-9

That night had been foretold to our ancestors, so that,
once they saw what kind of oaths they had put their trust in,
they would joyfully take courage.
This was the expectation of your people,
the saving of the virtuous and the ruin of their enemies;
for by the same act with which you took vengeance on our foes
you made us glorious by calling us to you.
The devout children of worthy men offered sacrifice in secret
and this divine pact they struck with one accord:
that the saints would share the same blessings and dangers alike;
and forthwith they had begun to chant the hymns of the fathers.
