{They say} (legousin). Vivid dramatic present active
indicative, as is natural here. {Fall on us} (Pesate eph'
h(886d)(8373)). Second aorist (first aorist ending) imperative of
pipt(935c), tense of urgency, do it now. {And hide us} (kai
krupsate h(886d)(8373)). Same tense of urgency again from krupt(935c) (verb
in verse  15 ). Both imperatives come in inverted order from  Ho
10:8  with kalupsate (cover) in place of krupsate (hide),
quoted by Jesus on the way to the Cross ( Lu 23:30 ) in the order
here, but with kalupsate, not krupsate. {From the face of him
that} (apo pros(9370)ou tou, etc.). "What sinners dread most is not
death, but the revealed Presence of God" (Swete). Cf.  Ge 3:8 .
{And from the wrath of the Lamb} (kai apo t(8873) org(8873) tou
arniou). Repetition of "the grave irony" (Swete) of  5:5f . The
Lamb is the Lion again in the terribleness of his wrath. Recall
the mourning in  1:7 . See  Mt 25:41ff.  where Jesus pronounces
the woes on the wicked.
