The seraphim approach Isaiah (Isa 6:6-6:7)

“Then one of the seraphim

Flew to me.

He was holding

A live burning coal

That he had taken

From the altar

With tongs.

The seraph touched

My mouth with it.

He said.

‘Now that this has touched your lips,

Your guilt has departed.

Your sin blotted out.’”

One of the seraphim flew over to Isaiah, holding a burning coal taken from the altar with tongs. This seraph touched the mouth of Isaiah with the burning coals. Then he said that his guilt and sin had been blotted out and gone away. Isaiah was made clean.
