The verse about the disobedience of the iblees

Ok. I know Al Baqarah 2:34 but there is something that feels wrong. Allah ordered angels to prostrate after Hz Adam but The Iblees isn't a angel? I have learned there is an rule in Arabic called Taqleeb (I like to see Quran as a... "Poetry Book" but the weirdness of Arabic makes me confused) but couldnt find it anywhere on the net from somewhere like a Arabic dictionary. I want an explanation about the verse itself and the name of that Arabic writing rule.
