Elisha left him and, taking the yoke of oxen, slaughtered them; he used the plowing equipment for fuel to boil their flesh, and gave it to his people to eat. Then he left and followed Elijah as his attendant. Kg. 19.21
O Lord, who hast mercy upon all,
take away from me my sins,
and mercifully kindle in me
the fire of thy Holy Spirit.
Take away from me the heart of stone,
and give me a heart of flesh,
a heart to love and adore Thee,
a heart to delight in Thee,
to follow and enjoy Thee, for Christ's sake, Amen
St. Ambrose of Milan (AD 339-397)
