It seems that God imprisoned the fallen angels who committed this evil sin, so that the other fallen angels would not do the same (as described in Jude 6).
Ni uwezekano kuwa Mungu aliwapeleka mateka hawa malaika walioanguka waliofanya dhambi, ili malaika wengine wameanguka wasirudie (vile imeelezwa katika Yuda 6).
