Tetzaveh 5773

There are two clothing pieces of the Kohein Gadol that the Torah describes to be "crafted by weavers" ("ma'aseh choshev"): the ephod (apron) and the choshen (breastplate). Why specifically these two? The Kli Yakar explains because they both atone for sins connected to one's thoughts, which in Hebrew is the same root as "choshev". The Ephod atones for idolatry; idolatry affects your faith and therefore affecting your thoughts. The choshen atones for corrupt judgment; a judge's thoughts are affected by his feelings in his heart.
