wares - merchandise, intellectual accomplishment that is salable.( 2 from WCD)
"Then they came again to Jerusalem. And as He was walking in the temple, the chief priests, the scribes, and the elders came to Him. And they said to Him, 'By what authority are you doing these things? Who gave you this authority to do this these things?' But Jesus answered and said to them, 'I will also ask you one question; then answer Me, and I will tell you by what authority I do these things: The baptism of John--was it from heaven or from men? Answer Me.' And they REASONED AMONG THEMSELVES (in their intellectual accomplishment?), saying, 'If we say, '''From heaven,''' He will say, '''Why then did you not believe him?''' But if we say, 'From men'---they feared the people, for all counted John to have been a prophet indeed. So they answered and said to Jesus, 'We do not know.' And Jesus answered and said to them, ''Neither will I tell you by what authority I do these things.’ “
(Mark 11:27-33)
These retained their wares in the presence of Jesus Christ who came "from heaven". As a result He would not answer their questions, and spoke to them in parables. (Mark 12:1)
"Therefore I speak to them in parables, because seeing they do not see, and hearing they do not hear, nor do they understand.” (Matthew 13:13)
