A fire of coals (anqrakian). Old word, in LXX, only here and Matthew 21:9 in N.T. A heap of burning coals (anqrax, coal). Cf. our "anthracite." It was cold (psuco hn). "There was coldness." The soldiers had apparently returned to their barracks. Were warming themselves (eqermainonto). Direct middle imperfect indicative of qermainw (from qermo). So as to qermainomeno about Peter. "Peter, unabashed by his lie, joined himself to the group and stood in the light of the fire" (Dods).
