the word is embrimaomai, that's the transliteration. I don't know how to type Greek in PB. Bibleworks says, "to be moved with anger, to be moved sternly." Aparently when this word is used in greek literature it has something to do with a horse snorting.
Liddell Scott renders:
13128 evmbrima,omai
evm&bri¯ma,omai, (evn) Dep. c. aor. med. et pass., to snort in, of horses, Aesch.
2. of persons, to be deeply moved, N.T.
II. c. dat. pers. to admonish urgently, rebuke, Ib.
But, I'm stumped right now, and I want to preach this right. I'm real close to just passing over. Was he mad at sin? Was he being sympathetic? Was he mad that they wept like there was no resurrection?
