Besieged

A benefic planet situated between two malefics, within orbs of each, is said to be 
besieged and therefore unfortunately placed. Some authorities restrict its application to a 
Significator when between and within orbs of two benefics. Older authorities, who applied the 
term to a planet situated between any two planets, considered a planet between Venus and 
Jupiter to be favorably besieged, but if between Mars and Saturn it was in an extremely 
unfavorable position.
