Jn 2:14b ... and the coin changers sitting.

The second phrase has these four narrator words, ... kai tous kermatistas kathēmenous (and the coin changers sitting).

The 4 words are top down. The animal sellers at the Temple could only accept Jewish coins as payment. Therefore the coin changers were there to sell the Jews who came from the surrounding foreign countries the current money of Judea at a premium in exchange for the pagan coins from where they came. The diagram shows thirty silver coins stacked up on two tables guarded by the two sitting coin changers. Now you know why Matthew used geometry when he decided the temple priests should hire Judas to betray Jesus for 30 pieces of silver (Mt 26:15).
