Second aorist active infinitive of did(936d)i, indirect command

Dramatic vivid present active indicative of leg(935c). {Take it and
eat it up} (labe kai kataphage auto). Second aorist (effective)
active imperatives of lamban(935c) and katesthi(935c) (perfective use

 Eze 3:1-3  Jer 15:6f . The book was already open and was not to

There is no reference in Ezekiel or Jeremiah to the bitterness
here mentioned. {Sweet as honey} (gluku h(9373) meli). For the
sweetness of the roll see  Ps 19:10f.  119:103 . "Every
revelation of God's purposes, even though a mere fragment, a
iblaridion, is 'bitter-sweet,' disclosing judgement as well as
mercy" (Swete). Deep and bitter sorrows confront John as he comes
to understand God's will and way.
