a) Being implies ones sentence (life) within (inception towards death)...an index "points out", hence index finger.

Same trick with prices...being implies evaluation (perception) within value (perceivable); while a price is being slapped on the outside to tempt ones evaluation within to sell out.

b) Compare (together equal) inverts "apart different". Drawing comparisons equalizes differences, which is why each jew draws suggestions to equalize differences among consenting gentiles.
