3O Lord, do not your eyes look for truth?

but they refused to take correction.
cThey have made their faces harder than rock;
they have refused to repent.

the lead is consumed by the fire;
ein vain the refining goes on,
for the wicked are not removed.
30 fRejected silver they are called,
for the Lord has rejected them.”

Hebrew and made their ears too heavy to hear
12 jThey made their hearts diamond-hard klest they should hear the law and the words that the Lord of hosts had sent lby his Spirit through mthe former prophets. nTherefore great anger came from the Lord of hosts.
