Mark 3:11

Whensoever they beheld him (otan auton eqewroun). Imperfect indicative with otan of repeated action. They kept falling down before him (prosepipton) and crying, (ekrazon) and he kept charging or rebuking (epitima) them, all imperfects. The unclean spirits (demons) recognize Jesus as the Son of God, as before. Jesus charged them not to make him known as he had also done before. He did not wish this testimony. It was a most exciting ordeal and is given only by Mark. Note non-final use of ina.
